LED Brake Light Electrical Issues

Post by DougEFresh1123 »



Calling all electrical experts, and for those of you not experts maybe a nice witty response to keep me from blowing up the Goldwing. :lol:

I am trying to convert my brake lights over to LED, using the 1157 LED red brake lights and am having issues.

Some basic background on my 1994 1500 SE, a previous owner installed a blinker relay into the brake lights on the trunk which would cause the brake lights on the trunk to blink when the the brake was activated, the saddlebag lights didn't blink.

This relay prevented the LED lights working as both running lights and brake lights, they did not become brighter when the brake was activated. I have disconnected the relay and returned the wiring to it's normal configuration, tested using the 4 standard 2057 incandescent light bulbs and they all work as normal, all four lights utilize the double filament and there is no blinking. When I change the bulbs over to the LED there is no visible increase in brightness when the brake is activated. As long as I have at least 1 2057 incandescent light bulb the 3 LED lights will increase in brightness when the brake is activated.

My son and I have tried various size resistors but haven't been able to get close to satisfactory results. We see minor increases in brightness but in my opinion not enough to get some ones attention. We are going to start checking the grounds, but wondering if there are other things to look into.

These are the lights we are using:

If the bulbs you are trying to use have only one contact on the base as shown in the picture on amazon I do not understand how they can possibly work.

What he said. But it looks like it was made to replace double filament bulbs with the offset pins.

It is possible I used the wrong link. :?
I'm pretty sure the bulbs have two contact points on the bottom but I will double check. As I said if I leave 1 incandescent bulb in the LED lights will get brighter when the brakes are activated.

It is quite possible I inserted the wrong link, I told my son to research and order the bulbs and he had the original lights on hand while researching. When I get home I will double check the lights for double contacts.
