I recently bought my first FD. Tonight was my first time using the headlights while driving. After having the compression tested I started to have issues on my way home from the shop. When I stopped I noticed that my driver side headlight isn't as bright as the passenger side. On top of that, while the headlights are on, if I use my right turn signal the front indicator doesn't work and the interior light flashes quickly. If I turn the headlights off the turn signal works just fine. Anyone have any ideas as to what may cause this? Not sure if it matters, but the car is RHD.

 

The difference in brightness could be as simple as a bulb and the turn signal thing could be f100 relay related. Is it cold where you are right now?

 

I figured that the headlight issue might be the bulb, but just wasn't sure if they were possibly related. I'm in Okinawa, Japan. It's mainly hot and humid here.

 

Nice... from my experience the f100 relay is sensitive to temperature. My car will do some weird things with the turn signals and headlights when its "cold" here in florida. Once the cabin of the car heats up, it stops. In addition to that if I pull the relay and put it in the freezer and then back in the car, the problems will come back until it warms up again. I would suggest starting with that and seeing what happens. Find seth Bronson out there...... he may have one or know where to get one

 

I planned on asking Seth in the morning if he had any idea what the issue could be. I finally got to meet him tonight when he did my compression test. Great guy and very knowledgeable.
