Blown lamp and check brake light
Hi guys and gals.
So my 95 that I purchased on Saturday was having electrical issues which I thought I fixed; front external lights were not working caused by the pig tails being disconnected, a few blown bulbs and presto fixed or so I thought.
Tonight I started her up and found the right hand fog light has blown which I just replaced, only the fog filament has blown not the indicator filament.
I am thinking that is why the pigtails were disconnected because the PO couldnt figure out why his lights kept blowing; I am not going to drive around in the dark unlike the PO; I will figure it out.
What could cause this? so far only this one bulb has blown, none of the others.
Also my check brake light came on while driving last night, didn't come on tonight though... what are some of the possibilities that this could this be?
Thanks guys and gals :-) you are awesome.

Hello,
Im going to recommend going through the wiring for all of your front end lights and find the wire(s) thats frayed and touching bare metal. This most likely what the problem is.
Other possibility is that your alternator is over charging the battery and your giving the lights too much voltage causing bulbs to go.
Run a test to see what voltage the foglight wire is getting. I think most normal bulbs will handle like 13.2 volts max.
