Headlights keep blowing

[67buggers]

Got a headlight issue need ideas...... Last year i had some angel eye type lights with seperate main beam and headlights, one day randomly both headlights blew leaving me just main beam and side lights. I now have vento lights and recently fly eyed and joey'd them but since doing this both headlights stopped working and again i only had main beam and side lights so i brought a pair of night breakers but when fitted they did the same thing and thats where i am now , only got main beam and side lights.... My mot is looming so needs sorting. Not checked anything yet as im a bit confused by it.

do you have to remove the reverse C shaped bridge from the relay board to run single chamber headlights like the vento ones? i no you do if you fit single chamber golf headlights due to this happening.

.?? Eh? My car would of had single chamber lights originally as its only a 1.4cl

Sound to me like a bad connection, possibly a wire that has cracked with age and is making contact intermittently

That'llbe nice and easy to find then!!

Just remove the bulbs, switch on the lights and touch the contacts with the multi meter. Compare volts and resistance. Should be reasonably easy. Get a friend to wiggle the wires. Especially where it goes into the connector block

Friend?! Lol nice obe ill give it ago

Just tried a working switch and that's not it, checked all fuses which are fine, after a bit of messing around the fuse box area I lost my main beam! It now intermittently comes on if I knock the fuse box in the right place which is suggesting bad connection somewhere....unless you guys know better?

when you had twin chamber ones, were they both on at the same time? then you got c bridge in there....

also have you measured voltage when the engine is running? could be that you alternator spits out too high a voltage.
