LED TURN SIGNALS

Postby RBGERSON » Fri Jan 01, 2016 8:04 am



I have a set of amber LED strips and was thinking of added them to the turn signals circuit by tapping into the turn signals wires just behind the turn signal housing. They are the tape backed kind and I was going to just stick them right below the turn signal lens on the fairing. Hide the wire going into the fairing as best I can.

The Q..will the LEDs effect the blinker relay and cause it not the flash???

You will be wiring them in parallel to the incandecent bulb which will lower the total resistance and they probably will flash faster.

So LED's blink faster because the resistance is lower?

I contend that you will notice no difference in the flash rate if wiring the LEDs in parallel with the incandescent lamps. I have LED mirror lights and fairing marker LEDs wired with my front incandescent turn signals and saddlebag and trunk side light LEDs wired in with my rear incandescent turn signals and see no difference in the flash rate

I paralleled some LED bulbs into my rear turn signal bulbs, and cannot tell any difference at all. The LED's have such a fractional amp draw compared to the incandescents, that the circuit apparently cannot tell they are there in any noticeable way. I suspect you will experience the same.

Your turn signals flash at a certain speed because of the resistance of the incandescent bulbs. If you add LEDs to the circuit, the flash should not change. If you replace the incandescent bulbs with LEDs then you will not have enough resistance and the flasher will act as if you have a bulb burned out. You can replace with LEDs, but, to have the flash appear about the same you would have to replace the flasher with an electronic flasher or add a resistor inline with the LEDs. If you replace the bulbs with LEDs you will lessen the drain on the charging system and the LEDs will last the lifetime of your bike. I have replaced all my bulbs with LEDs that I found on ebay and I am completely satisfied with the results. If you are interested, the link to these LEDs is here; [url]4x 1157 High Power 2835 Chip 1400LM White Projector Turn Signal LED Light Bulbs[/url]. They are really bright. Hope this helps.

Not looking to replace the OEM bulbs just add some more flashing LEDS to the front and back of my bike for visibility for little old ladies..but maybe I should replace all the old bulbs with LEDS..while I am in there. With my luck if I don't after I button her back up the old bulbs will fail the next week!!! :lol: :lol:

But if I replace all with LEDS don't I have to change the flasher to an electronic type so the lack of resistance isn't an issue///

I got the information from here.
https://www.swtc.edu/ag_power/electrica ... uits.htm#4

"As you add more and more branches to the circuit the total current will increase because Ohm's Law states that the lower the resistance, the higher the current."

The higher the current the faster the turn signal relay will flash.
Odd thing is I have a couple of those LED strips and I put an Ohm meter across them and didn't read any resistance. I tried both digital and analog meters and reversing the leads and still no readings on any setting. So, to my surprize, they may have a minimal affect or not affect the his flasher at all.

Will all depend on how you install them...series vs parallel.

The strips are so low resistance wise, you probably won't even know they're there...the flasher certainly won't. It's looking for what, 50W and if it doesn't find it, it won't flash right. Keep at least 2 bulbs original, and you won't change the flash rate. Remove one of the 2 bulbs in the 'system (front and rear signal) and you will change the flash rate. Remove both and replace with LED's, you might not flash at all. (yeah ask me how I know)

I've replaced all the flashers (PO had near everything on the sides and front/rear as flashers) except the back 2 bulbs...and even with 2 of the replacement resistors I flash too fast. Electronic or LED compatible 'flasher' relay is next. Of course, a molex connector will need to be made to fit it to the bike, but it's easier than putting a pair of resistors on each circuit to make the flash rate 'right'.

Is there a "Plug n play" electronic flasher unit that will satisfy the problem or a particular flasher unit anyone can recommend for complete turn signal conversion to LED?

Standard flashers use resistance through the bulbs and heat, because of that resistance, to open and close the contacts (switch) in the flasher. Since the LEDs don't create enough resistance, the flasher doesn't heat up enough to stay on or off very long. Therefore if you replace the standard flasher with an electronic flasher, you should overcome that problem. The electronic flasher is electronically timed instead of being controlled by resistance. Try any local auto parts store.

I understand the theory, I"m wondering if anyone is aware of a part number of a flasher unit that is a direct swap out without fabricating a connector to make it work, if it's out there at all.

I have been looking for one for the GL1500 but have had no luck. I have replaced the flasher on the GL1800 with one from Cyclemax and it works perfectly. The problem is, I think, the self cancelling feature designed into the Goldwing.
I think the easiest option is the load equalizers for the turn signal light circuits.

That might just be the simplest way to do it, one at each end of the bike front and rear, cut and dry. As I understand it, the flasher unit is a bear to get to under the trunk anyway and the point of questioning this whole issue is to find the best alternative. I have another brand of load resistor that I'll try out on the front signals first because of easy access. Thanks again NVSB4!! :D

I do like the self cancel feature, I'd hate to lose it. I will go with the load resistors, thanks Mike!

Correct. You can replace the flasher with an electronic one to get your LEDs to flash correctly, but you will lose your auto turn-cancel functionality. This is why I just left the OEM flasher in place and installed some high-power load resistors when I installed my LED signals.

Hey thanks for the link! I looked a few of them over and read thru customer reviews, but didn't see anyone that used it on a Goldwing, possibly because of the hassle getting to the flasher under the trunk, which is why I'm thinking I'll go with the equalizers front and rear instead, less dismantling involved, but I do appreciate you going to the trouble of looking. If at anytime I decide to go that route, I might try relocating the flasher to a more convenient spot for future access.

That is reason enough for me! Hey has anyone tried relocating the flasher unit for better access? Saddlebags maybe?

The turn signal flasher relays aren't hard to get to.

Why does it say "Remove the trunk" in the first step?
I'm pretty sure they are mounted to the cross-member under the trunk.

Excellent question. I'm pretty sure that I've seen them and I've never had the trunk off.
I may be eating my words, but I'll pull the seat tomorrow and take a picture of my own.

My 99SE has them under the trunk.
You don't have to 'remove' it, but you do have to loosen it by removing all the bolts that hold it to the bike. I didn't have to remove any wires to get to it. Support it with a chunk of 2x4, and you can reach in. It's on the right hand side looking from the seat back. 4way relay is on the left.
(again, my bike, as it is right now. no telling what your bike holds in store for you!)

You can't get to the relays just by removing the seat. You have to at the very least loosen and lift the trunk.
