Autozone carries leds. bend over when you walk in to save time.

Their site says they will be getting new stock August 30. That's a ways away.

That said, next time I have mine apart, I think I am going to replace my blue illumination LEDs with "cool white" instead. The blue does look cool, but anything red on the dash (i.e. tach redline, gas/temp redlines) disappears at night.

I completed mine today!

I purchased the 20th Anniversary edition Aspencade the July 4th weekend and have been gathering items to fix many of the little things I didn't like.

Today I tackled the LED changeover. I had ordered everything from this outstanding instruction (but I found I was missing a red bulb for low oil pressure that I never see mentioned in the bulb list unless I missed it).

I opted to use regular bulbs for those three systems identified as needing resistors, etc. I have the resistors (I ordered everything using the links provided, thank you very much) but because the wiring was a soup sandwich I opted to not tackle that aspect as yet.

I, too, had a windshield screw that was too tight or stuck. I found that I could use the bigger Philips head in my small drill and it was able to buzz it right out!

The biggest pains were the top screws for each mirror. They were not easy to get to removing or reinstalling. I took out the fairing pockets which made it easier to remove the vents, I could reach from under to push the tabs plus the pockets were raised resulting in the bottom of the vent hitting the pocket and stopping it from coming out.

The speedo cable didn't want to thread in easily so I tilted the dash with the left side down (as viewed from the seat). This allowed the best position to ensure the square end fit properly back in and to allow the threads to catch for the knurled knob to get it tight. Also turn your handle bars all the way to the left to get the most room for your hand and arm when doing this.

I could never get the bike to light the OD light during testing, even switching back to standard bulb. I tried shifting up but could only shift up to fourth gear, it would not shift the last notch to get the OD light to come on. My bike did not have the top threaded nuts on the dash cover seen in the photos, which made it want to tilt forward (no holes for them either) towards the rider until I got everything else installed. I removed the ignition cover (the big center piece) and the two smaller pieces that cover the top of the forks to do this as well. It gave better access to work in there.

MANY THANKS FOR THESE PROCEDURES TO HELP US WORK ON OUR OWN BIKES.

I have a couple of questions. I would like to change my dash lights to LED but I don't want to spend $60 on new bulbs only to find out they are the wrong ones. It seems that some of your Do it yourself articles cover different GL 1500 years. The cornering bulbs for instance were different from the ones that I had in my 1990 GL 1500. A second DIY was put up on the same change, but this one covered the bulbs that were in my bike. How do I know all the bulbs on your list are accurate for my 1990? Don't get me wrong, I love the articles, but the bikes vary from year to year and so do the parts used. The only way to find the correct bulb is to tear it apart and match the bulb on superbright LED's. Then I have a garage full of pieces waiting on the bulbs to come in. The tupperware all comes off about the same way on teardown, but is there any way that when you write up a DIY that you could give the years of the bikes that the change applies too. Thanks.

I'd love to - but I don't have a stable of bikes to work with. I try to look up in parts lists, older years service manuals and so on to make sure differences between model years are covered - but I don't always know for sure. Sometimes I depend on others who do the same thing to their bikes to report differences.

In the case of the dash lights, I think you're fairly safe - to my knowledge, the dash light usage is identical throughout the model years.

My bike is a 1996 GL1500 Aspencade and I used this following list to do mine...

Prepared -- June 19, 2013

This is a list of the bulbs and part numbers from superbrightleds.com
Turn Signals (Amber, Qty 2): 74-AHP
Main Illumination (Blue, Qty 4): WLED-B6
Top and bottom LCD Illumination (Blue, Qty 2): 74-BHP3
High Beam* (Blue, Qty 1): WLED-B4-32

Overdrive*, Side Stand, Low Fuel, Cruise Set, Cruise On (Amber, Qty 2): WLED-A4-32
(Note: I did not change the Low Fuel, Cruise Set or Cruise On as they need resistors inline or they will not work properly – I left mine alone; or you could change them to a new 194 or 168 wedge base bulb but LEDs create a problem)

Neutral (Green, Qty 1): WLED-G4-32
Reverse (White, Qty 1): WLED-W4-32

For the Main Illumination LEDs, they tend to put out very narrow, directed beams of light, causing bright "hot spots" on the tachometer and speedometer dials. I recommend either filing down the tops of the LEDs, or gluing a small piece of white paper (or plastic from a discarded bottle to diffuse the light) to the top of the LED, in order to diffuse the light and eliminate the hot spots.
(Note: From my experience the *HIGH BEAM Blue light tends to be VERY bright at night and NEEDS the plastic diffuser idea applied – as of this writing I have not done mine – but will someday. The *OVERDRIVE light is also VERY bright so consider doing this modification to that one as wel)
Postings are my opinions based on experience and acquired knowledge.
Your results may vary. Universal disclaimers apply.

I bought all my different color LED lamps from Hong Kong, sure it takes three weeks to arrive but they are really inexpensive, my advice is to get at least the 10x quantity, and the ones I get are just rounded with average output, I saw no need for multiple emitters on the bulbs like for running lights on a car or truck. Even the blue and amber smaller base LEDs were cheap such as the amber TS indicators and the blue LCD lamps.. I just took a black marking pen to the top of the Hi beam blue LED so as to draw down its intensity. Since the lucite backing plates for the gauges need side light from the LEDs I may just super glue some small pieces of tin foil to the top of each illumination LED, they do light up the dials pretty good otherwise.

About the three lamps for fuel and the cruise control I was not aware they had to be a resistance load, may just put some 194LL (long life) bulbs back in them. Or just wire in a parallel lamp socket connection to 194 bulbs and still use the LEDs in the gauge. You would have bulbs on the circuit there behind the dash but the LEDs are in the dash, I had to do a similar wiring application to the third brake light on my Silverado because with an LED light my cruise control failed to work. A load resistor could work but I would be concerned about it getting hot and melting the dash.

If a person has time ordering from China or Hong Kong on Ebay is the way to go, get plenty of these lamps as one out of ten on average is a dud.
And keep just one handy marked + or- on the base after you have it installed and use it as a reference for any light you don't have a constant power source such as the OD, that way you can orientate the larger cathode which is - to the brown wire (ground) side of the socket, feel free to correct me anyone, I think the smaller part the anode in the LED is positive, the larger cathode is negative.

I saw on a different website that replacing the amber turn signal bulbs causes the self canceling to stop working on the blinkers? Is this correct. I think the bike they were reffering to was a newer 1995 SE.. I have a 1990 GL 1500.

Hi

I do not think this dash light bulb will affect the flashing sequence there are many other bulb on the same circuit if you replace front and rear I do beleive it will . I will sure know soon i just pulled mine (99 SE) in the garage for the winter and I have received the LED bulbs as per the list on this post soon I will repost saying the results.

If you are replacing just the turn signal lamps in the dash with LEDs, it is not enough of a difference in current draw to make any change in operation.

If you also replace the front/rear turn signal bulbs with LEDs, you will need to add a load resistor in order to maintain the self canceling function.

We used your instructions to disassemble the dash to get to the back speedometer, the cable had worked loose. The speedometer quit working, we replaced the cable hoping that was the problem, no such luck. Taking the dash apart is quite involved, but with your step by step instructions and patience, it can be done. Thank you so much, we are still speaking!
Fantastic job!!!

Reading through this article's responses, I noticed a couple of people have experienced problems with the mirror securing screws, I had the same difficulty and overcame it by replacing the screws with socket headed ones, it's much easier to remove/refit them using the ball-ended Allen keys.---Brilliant article with a great deal of valuable information, Thanks.

Note: I've received a report that some GL1500 use red for the low fuel lamp, instead of amber. You'll want to adjust yours accordingly.
For reference, here are a couple variations to the Dash light colours on a 1990 GL1500 SE;

Low Fuel - RED,
Reverse - AMBER.

Although I have not yet pulled apart the Dash to do this mod yet (perhaps this winter if I have the spare cash for the bulbs), to my eye it looks like the illumination lights are likely WHITE. The white light would help deal with the Blue and Red in the gauges and the Gauge Needles, Odometer and Trip counter are all lit white.

Looks cool to me, I did all this to my last 1500 when I had to replace the LCD panel, seemed a bit daunting at first and there were a considerable amount of bits everywhere, but it was easier than I thought with the forum info. I was amazed at the difference.

Sadly the 1800 has not improved any.
If at first you don't succeed, hide the evidence.

Sadly I couldn't do it, I did everything except remove the windshield, the left side had give but the right absolutely did not, there's no knob on the right but this sort of dock or something, pictured here


This dock appears to be the point where it won't move or bend, and I can't see any way or removing it or manipulating it, and it's also wired in.

If you're talking about that cigarette-lighter-style plug, they normally unscrew from the back. Reach in and unplug the wires, then unscrew the sleeve around it. It will then pull through from the front.

Oh thanks, I guess I didn't twist hard enough when I tried, but then none of this has been touched by the previous owner so I guess it's been set for 26 years. I followed the guide but I worry I'm missing something else, do I have to take everything off from seat to dash, and also remove the windshield? I couldn't for the life of me get the windshield to budge if it absolutely has to come off.

Okay no reply, but I'm at it again and I can't even get any kind of grip on it, the vent is completely blocking me and the plug will not budge

I had my windshield off when I did mine, it might make things easier for you to get to and help loosen things up on the glareshield if you did remove the windshield.
