I have 4 hellas behind my grill on different relays and switches, one set is not working anymore and I don't know why. I bought a new realy and still nothing, the fuse is not blown, the bulbs look good, and all the wires seem secure. Could the actual switch be bad? The led lights up when it's on but just not the lights.

Anyone have any ideas or anything I can't think of?

Thanks

 

You need to check for voltage at the lights to see if 12V is getting there or not.

 

Agreed, time to get out the meter or test light and start probing and testing for voltage.

 

Not likely to be the switch itself unless it's a bad connection. Are all four hooked to the same switch? If so, you may have melted the switch depending on how heavy of a switch you are using. Other than that, refer to what was suggested above.

 

^ no I have two switches for each set. I'll go get a voltage tester since the wireless one I have doesn't seem to work on car wires.

 

a 12v test lamp will also do the trick
