Dim brake light.

[godawgsdv8]

I just replaced my stock tail lights with led's. I made sure I have a good ground. Blinkers work fine. My brake lights when brake applied is very dim, anyone know if the flasher or brake switch needs replacing? Looking for help.

Thanks.

No, you have some other issue. Either the lights themselves or wiring.

Sounds like the tail and brake light wires are reversed.

Try measuring the voltage with a volt meter.

I was going to say 24v bulbs on 12v system but the less should be omnivolt.

Sounds like something isn't right.

Get the vmm,soldier b and a beer.

I had dim brake lights on my deuce tractor, was only getting 14 v to the connection.
It was a bad brake light switch causing the low voltage.
Replaced switch, problem solved!

Still need some help, Tested the switch that's not it. Every light works but the brakes, even on my 105 it's the same way. Any suggestions?

I just replaced my brake light switch. The brake lights were not working. I had a buddy push the brake and the switch only dropped to about 700 ohms. It should have dropped to near zero. Now that it was replaced they work fine.

Put one of your old incandescent housings back on one side. Then have someone hit the brakes and compare the 2. If the incandescent light works properly and the led one doesn't then I hate to tell you but your led lights are bad.

If the incandescent light is also dim then you will be hunting for a short.

I had similar problems with trucklite led turn signals. The leds made for the military suck. It doesn't seem to matter what brand either.

Starting my research... my tail and brake light wires are reversed, looking to identify one from the other.

My tail lights are VERY bright, but the stop and turn lights are barely visible when running lights are on.

Reversed my tail and running light wiring, works great, now air/brake switch starting to fail.
