I just noticed tonight that my headlights aren't working. I have an h4 conversion with wiring upgrade. Not sure what could be wrong. The inline fuse is good and bulbs are good and connections are good to them. What else could be wrong?

We have had a lot of moisture in the air and everything has been very damp in the air. Not sure if that could be a problem, but they worked last night. Anything else to check? I know there are 2 relays up there as well, but I have no way of checking them at the moment. Anyone ever had this problem?

​How sure are u that the inline fuse is good?​​​​​​
Need a multimeter. Pls see signature.
Does stock circuit work? Test by connecting bulbs to stock connectors.
How sure are you that your connections are good?
Info on your H4 conversion?
What wiring upgrade did u do?
Did you check the stock fuses?
Does the stock headlight relay click?
Do the H4 relays click?
Do the tail lights work?

Rally lights have no warranty on your issue? If not, got schematics or info from them?

 

False alarm. I could hear the relay click when I would turn the lights on, but no lights. I decided to start simple and pulled the battery terminal and give it a good cleaning. I had the power wire with an eyelet end on it connected to the battery cable end bolt. I touched it to the post and they worked. A simple re-wire and im back going again
