Headlights very dim when on dip

On my hymer 754 the headlights when on dip are very dim, I have had it checked for voltage drop and that was OK and was advised to replace the bulbs with some of a higher wattage, the M/H is a 2001 model with the twin headlights, can anyone tell me what type of bulb they use? ( H4, H!, H7 etc ) or has anyone had the same problem and sorted it. The bulbs are very difficult to get to and I would like to get the bulbs and then have them fitted.

Have you had it checked for bad earth that can also cause dim headlights.

Hi kencocamper,

Don't know your bulb type, but I use a firm called www.autobubsdirect.co.uk

bulbs at about half the halfords price. they sell bulbs which have a brighter output as well. very prompt and reliable service.

they helped with my old 340 volvo and my mates range rover both of which were very poor at illuminating the road.

Do halfords offer a fitting service which would take some of the grief out of a change over?

I have a B694 and my headlights are the same, even with 100 watt bulbs (H1). I have looked into replacing the headlights with no success I afraid, if you have better luck than I do please PM me.

Regards
Andy

Hi

Our Hymer has the twin small round lamps. The dipped beam units have a projector lens which can deteriorate with age or use. My five year old Volvo V50 has similar lamps and the lenses turned opaque over the years. Had them changed a couple of months ago and the difference is amazing.

I,m sure I have read on the forum somewhere that Hymer fit or can be replaced with Hella units. Hella are at Banbury in the UK.

it's illegal to use the higher wattage bulbs on our roads, the max has to be 55w. How they'd find out if you used anything higher I don't know. I've got Ring Xenon Max fitted in mine which are about the brightest you can fit and still be 55w.

dim headlights when on dip

Hi all, thanks very much for the replies.

KEV-if it was a bad earth would that not cause a voltage drop.

DAVY- thanks for that, I do have someone who will fit bulbs, but is
that the problem.

ANDY-if 100w bulbs isnt the answer it lookes like mcpezza has
only way if sorting this.

MIKE-thanks for that Mike, the headlight units fitted are Hella and
when I rang Hymer UK they said replacments where £269.


I will give the Hella place a ring tomorrow.
many thanks
Ken

Hi Ken Hella will not supply a replacement light unit, as they only supply Hymer , i did try to get the inner of the two lights replaced in January this year
Hymer UK quoted £99 I went to Campirama and got one for 75euro
