I started a thread titled "4 hi mod no worky" so I didn't over run this one, but no I didn't. I've replacedchecked everything though. Bat + to 30,bat - to 85,87 to lows and 86 to hi. I did use but connectors.... But my lights work fine, I'm thinking bad relay

You might have burnt up the relay

NO!!!

So would you guys agree that the 20 amp relay that the previous owner put in my truck for this mod is probably too small and the culprit of my issue?

im thinking 20 amp is what mine is... lemme double check..

i have the 4-hi kit from LMC and the amperage isn't listed :/

im pretty sure it's 20a though

hmmm...so could the relay just be bad, then? It acts almost like when I pop the brights on it gets hot and stops working (low beams go off) then it works again once it cools off (low beams pop back on) and this just repeats whether I'm moving or sitting still

kinda what it sounds like.. but on a better note, they're cheap to replace.

OK, I'll stop by Radio Shack and just grab a 20a relay then and see what happens since you're running a 20a relay. If that doesn't work for some reason I'll bump it up to 30a. Thank you, sir!

my relay is either a 30 or a 40... I can't remember though.
