Re: Blown bulb warning light
I may be wrong on this but h6w bulbs are xennon led bulbs??? If so some bulb monitorin units dont like led bulbs and makes em mad, sends em silly and gives you all kinds of bad readings. Eddie Stobart has some older smaller Volvo tractor units with bulb monitor units fitted as standard equipment and if you couple up to a newer trailer with the new style led lights then when you turn on the lights every light incliding the ones on the unit makes the thing look like the outfit on the xmas coke advert lol flashing like a xmas tree pmsl. The way they sorted that out cost em a fortune, they had to fit new bulb monitoring units to the tractor units.
So make sure the buls you fitted are of the correct type and not led type?
