Headlight bulb

[Matthew23]

Hi everyone im new here! Recently purchased a 2003 1.9d berlingo, i bought it with a problem with the drivers side dipped beam not working, although the full beam still works? Ive swapped new bulbs, checked all fuses and cant find anything! Please help as im new to the van scene and need it for work ? thankyou!

It's got to be a break in a wire if the bulb and everything else is good. Time to start digging I'm afraid.

Thats what i was thinking mate, is there anywhere they normally break from rubbing against something els or anything like that? Cheers foe quick reply too! ?

ouch.

Those wires are routed through the driver's side front fender(well, that's the lefhand side on my car, but i drive on the right side of the road.) if I'm not entirely mistaken.
that means they're a pain to follow, and even to tie a new one on and drag it into place with the old is going to be a hassle.

You may instead want to consider upgrading the van slightly.
A couple of years ago, I picked up a wiring kit which had a set of relays and bulb connectors.
It attached directly to the battery, to the relays, and on to the bulbs.
the relays were hooked up to one of the old bulb connectors.
The wires are all thicker than standard, and they're shorter, since they don't have to go to the relay inside the coupe, so should in theory give slightly better light because of the lower voltage drop.

The nice thing about it is that it doesn't specify which side bulb connector you should use to hook it up to the original wiring.

whether or not it actually improves lighting to a measurable degree is debatable. But it's possible for anyone to install something similar.
(with a possible exception if there's anything to do with can-bus connected to the lights)

Thanks for the reply mate, do you have any links for the kit you used? Cheers matty

I'd try breaking into the wire to the dip beam that works and take one to the other light just to get it working if it's going to be difficult. Cut the old wire and tape it up for future reference.

most likely broken where the lume is clipped or routed through the bulkhead. I would consider running in a new wire outside the lume.

The kit I got is no longer for sale.

Here's a similar kit I found on eBay;

Lots of mumbo jumbo and Chinese misunderstanding, but it looks pretty close.
No mention of the wire thickness, though.
