Turn signal lights to LED's

Post by Paulreiziger »



I am working to change all the lights on my '96 1500SE to LED's.
When I changed one of the rear turn signal lights the relay went crazy (as you can expect when the load is reduced.
My first reaction was that I would have to change the relay into one that is load independent so I started looking and reading up on the issue.
It turns out that I could upset a lot of other electronics in this circuit by simply changing the relay and lights.
What is the best way to not get into trouble?
- Simply use load resistors and forget about making the alternators life easier?
- Change to LED and change the turn signal relay (but maybe have a whole lot of other issues at hand by doing so)?

Any idears on this fellows?

You can switch out the relay, but you will lose the turn signal auto-cancellation feature by doing so.

My solution was to put a load resistor in parallel with each LED. It doesn't pull as much current as the incandescent bulbs, but enough to make the original relay function, and keeps the turn cancellation circuit happy.

Thank you admin,
Do I need 2 or 4 loads?

I used two - all the lights are connected in parallel, so you don't need to use more than two. I fastened them to the frame at the back of the bike to use the frame as a giant heat sink.

Good idea, I'll do that. Thanks a lot.

My GL1500 is a 1998. I replaced the saddlebag run/brake light assemblies with run/brake/turn light assemblies. I replaced the standard lamps in the turn signal assemblies in the saddlebag assemblies with LED's. I kept the stock turn signal lamps in the trunk and fairing. So I do not have the turn signal hyper flash that you would experience with all the lamps replaced to LED. My turn signal relay is OEM.

I could have replaced all the turn lamps to LED but that would have required adding additional load resistors. Adding load resistors pretty much negates the current draw savings of going to LED's in the first place.

I do have all the run/brake lights changed to LED as well as my headlights. These are the lamps that are the biggest constant draw of current. The current draw by the intermittent illumination of the turn signals really does not concerne me. I also replaced the fairing, trunk and saddlebag side marker lights to LED strip lights.

I see that you have a trailer. If you haven't done so already, install LED's in your trialer light assemblies too.

Thanks a lot MikeB, the trailer is the next thing I will convert into LED.

Thanks a lot fellows,
I ordered a couple of load resistors and that brings me to my next question; where to best place them?
I know I need the orange and light-blue wires coming out of the turn signal switch but what is the best place to pickup these wires and insert the resistors?
Anyone know a good place and why is that?

Thanks again.

You might PM WingAdmin and ask him where he wired them in. He said he mounted them at the rear of the bike on the frame to use as a heat sink.
