H7 bulbs keep blowing

Featured Replies

Since I've got my Elegance I have one permanent problem, deep beam bulbs keep blowing every 1-2 weeks. They never gone both in one time, left-right, right-left etc

Fuses always OK. I stop using a good quality bulbs cos they are cost 20 quid for pair so can not afford that but cheap ones going quick

Any idea???

Thanx

You are not touching the lamp with you fingers when fitting them are you?

Measure voltage at battery terminals with engine running.

Spikes prevented by the fuses i think

A friend of mine had this annoying problem with his Honda. Finally one guy told him to change BOTH bulbs when one is dead. I don't know why but it helped.

Looking for the decent bulbs again to try one more time. Thank you

Try some heavy duty ones.

Had to get some for my old Volvo as the headlights were on all the time.

Standard bulbs didn't last long.

Depends if you have this feature or not, but I found with coming home lights enabled this would kill my bulbs in a matter of a few months.  Soon's I disabled coming home and leaving home lights they have so far lasted well over a year.

I've had a couple of Volvos (with HL DRLs) but never replaced any bulbs. There's probably more to it than just being on all the time.

My vRS is just 3yrs old and it's had the "home" lights from the start but it's never caused any bulb issues. Seems that even cars of similar models differ greatly in faults.

 

Now HIDs, that's another matter! (eh Mike H  :swear: )
