LED H4 headlight bulbs

Postby SilverDave » Wed Feb 18, 2015 9:06 pm



LED H4's ...

Are these safe ? Do they work reliably in a motorcycle ?
Do they give as much light as my " SilverStars " ?
Do they get too hot for a GL1200 reflector ?

Is it worth replacing the bulb ?

I would be interested in hearing feedback on this, A typical H4 bulb puts out between 1100 and 1500 lumens, both of these LED options claim to be putting out 1.5 to 2x the number of lumens, so should be brighter, but what is claimed and what they actually do are 2 different things.. Would like to hear from people that have actually used these bulbs.

Incandescent lights produce light by heating up a filament until it glows, that heat is kept within the enclosure.

High output LEDs also produce heat, but they have to be kept cool, or else they will burn out. So the LED chip is mounted to a metal heatsink, which conducts the heat out the back of the bulb assembly, where it is radiated (usually including a small fan) into the area behind the bulb. If that's surrounded by ABS, it possibly could be too much heat. But I haven't heard anyone report about installing them, so I don't know for sure.

I have 2 1984 GL1200A's and in one I upgraded the oem bulb to a Sylvania Silverstar, there was some improvement. The following riding Season, I replaced the H4 in the other GL1200 with the H4 LED advertised by Big Bike Parts, ( there is a YouTube video ) it was about 69.00 and it is bright, yet I found my bike was not safe to drive outside the city at night because there was little to no down the road light. Two other friends of mine shared the same experience, one fella also has a GL1200, and the other fella has a GL1500 requiring two of the same H4 LED's, We also noticed that on turning on the Highbeam seem to Lower the light, we felt like the bulb was installed upside down, but that can't be the case because the bulbs are keyed and can only go in one way.
If you only drive in the Day, or In the City at Night the bulb is very good and the dash lights even seem brighter because of the huge change in the amount of draw on the system. However I found I could not drive on the highway in the night time without my driving lights on. ( 2 X 55w Picca Bulbs, mounted on light bar just above the Rad. )
Also note, my Stator is in perfect working order. I tried the LED H4 as a preventative measure.
I have decided to follow what other guys have done, and had great success with on GL1200's,,, I will be installing HID System before our riding season starts.
Good Luck, let me know how you make out.

Sorry, I forgot to add, the H4 LED bulb was not hot, in fact it was cool to the touch. Also, it was a simple matter of remove the old H4 bulb and plug in the H4 LED, no mod's required. It's a pretty simple job.

Thanks Derek ... thats just what I wanted to know ...

My guess is that incandescant's have an almost pinpoint light source and the parabolic reflector does its job of throwing light a long way down the road.
( and I do love my Silverstar headlight bulb !!)

.... while LED's are more diffuse and just cannot throw the "focused" light as far

Maybe we have to wait until they re-design headlight reflectors for a 1200

I installed the so-called 3200lm led headlight last year. Remember, its not just the lumen output to watch, its the pattern in which the light is emitted. unless it perfectly matches our halogen headlight, the reflector and lens will not properly focus the beam. so even if you have 3200 lumens output, the effective light put down the road in front of you may be less. Not to mention possibly blinding oncoming traffic.

Update on Replacing the H4 Led with HID
Wow,,, enough said,,,
if you know what your doing, or have a little help, expect the change over to be 1 or 2 hours with minor mods to the existing housing, no special tools required.

there are two reviews an 1100 and 1200 goldwing of this LED light being used am giving some serious thought to trying it out, based on the reviews, the reviewer for the 1200 suggested it doesn't interfere with the radio or cb which is a bonus.

I talked extensively to a dealer who sells HID's AND LED's /

My 1200 has a vertical diffuser pattern on the lens , and it was his considered opinion that you need almost a pinpoint source to throw the light properly down the road , thru that diffuser.

Pinpoint : ... like the original H4 Halogen or possibly like some modern H4 HID's.

Do let us know if your new LED H4 is bright enough (Probably) and whether it throws focused light down the road ( ???)
