looking at getting some light bars fitted to my new volvo fh500 version 3 but ive heard a lot of stuff about them having to be programmed in to lighting ecu by volvo workshop.
does any body know if this is true or can they just be done diy.
if they can be done diy do you have a how to??
im concerned about the cost volvo charge, my mate had his 55 plate fm done at volvo and they sent him a bill for a grand so with light bars costing in the region of £500 to £600 im not too willing to pay volvo my hard earned cash.
and no im not just wanting them for looks im on the bulk and they really make a difference finding those wee farms in the dark.
