Patrick - LED Taillight problems

[glenview289]

Some time back, about 3-4 years ago, I converted my Unique to LEDs. At that time there was discussion about the low current draw of LEDs that would notwork with some trailer relay switches. I'm sure a search on this will bring up something. Not an EE, but do remember this could be an issue.

To help Bliss with his tail light/trailer relay problems, I went out and measured the voltage drop across my trailer relay (with the circuit operating, of course). My stock trailer relay was eating up 1.7volts with the battery source putting out 12.5volts. There are better relays than our "stock" ones. They are touted as "heavy duty" trailer relays. He's had problems before with his relay, too. Some of the guys in other forums report voltage drops of well over 2 volts for some of the relays.

I remember that thread...didn't the end result be that a resistor had to be added at the back of the car for the lights to work?

It's been a while, but there's that dim memory, perhaps I'll go back to the Unique website and see if I can find the thread.

Cheers!
