Headlight Problem

Hello all

i have been searching this website for a few hours now and have not found a problem the same as what i am currently experiencing.

The headlights work fine but every now and then (lately every time i drive it at night) the headlights just turn off and then return after a few moments.. i loose the parking, headlights, high beam and also the spotlights.

A few scary moments driving to work at night i give you the big tip.

So... i am going to pull the switch out and investigate the female plug as many have mentioned previously in this forum, and investigate the headlight relay modification.

Is this heading in the right direction blaming the plug to the switch mechanism? can the plug be repaired if found to be the problem? where would i find a new one to replace the old?

Can someone direct me in finding the correct way of doing this relay wiring mod?

Cheers in advance

First off, Welcome to FTE...

I would say you are heading in the right direction with your diagnosis.. The headlight switches are known for having the thermal breaker go sour (weak) just pop in a new switch, and check the plug as you mentioned if it looks like it has been hot grab one at the parts store when you get your switch.

The relay mod takes a lot of load off of the switch and results in brighter lights, so it is a good mod..

I agree with White. Sounds like the headlight switch. While you are in there, check the plug and wiring for any sort of damage.

yeah i was just talking to one of our older gents at work here and mentioned some have a thermal breaker due to the resetting after about 30 secs...

First i have heard of this... but something new everyday.

I will rip it out this afternoon... it is a pretty dangerous situation to be in at night with lights tripping.

that wiring mod would be awesome... still cant find it
