Led fastflash

psduser1 · Dec 30, 2016

Dumb question, but I'm stumped.
I've got led taillights on my 00 dually. Changed the relay,everything worked great.
I put led tails on the 01, changed the relay, and still have the fast flash. What gives?
Using the ep27 relay.

Maybe a bad relay? Have you tried wiring in a resistor to see if that fixes the problem?

psduser1 · Jan 2, 2017

I havent.
All I did was throw in the relay. Didn't work, pulled it back out. I haven't really had time to mess with it. I was hoping there was a simple "duh" moment, lol.

resistors are sometimes needed

try flipping the bulb

At the socket? I thought they were bi-polar?

yeah, sometimes works

you can fix that with a LED flasher. I bought one from superbrightleds,com The leds use less power that is why your current flasher hyper flash's

get a resistor from napa and put it inline & it will eliminate the fast flashing from led's just did it for one of our rollbacks

If he's using the EP27 it shouldnt flash. Ive done several trucks with the relay and never had an issue. BUT that has always been going to a bed with oval LED's, not stock replacements. I'd try another relay and see what it does.

I really hope to avoid that, lol.

I think I'll try this first.
These are grote 4" round rubber mount lights.
