    Had a wander through Halfrauds at Lakeside today. (BTW, seeing as it was Black Friday, the store was deserted!)
    Came across some DRL's which were interesting. As I don't go in to the store much, I hadn't seen them before. Basically, there were varying packs containing two strips of self-adhesive contour-mouldable LED's with a few wires attached to a miniature box. Didn't look like there was much cable in terms of length.

    I've always fancied having DLR's on the MH. Got integral ones on the car and they look the bizzo as well as being a safety feature etc etc.

    Anybody seen these after-market lights? Bought them? Fitted them? Costs a packet to have them done professionally and the wings of my MH have to be removed!

    My other question is; how do they affect the Canbus sytem? I remember my alarm engineer telling me that, "You can't just scotchlock and hack into wires like you used to y'know....it upsets the ol' zeros and ones of the canbus". (Whatever that means?)

    If they are similar to the aftermarket ones I fitted on a mk7 transit you will need an ignition or engine run supply... I chose engine run to prevent them switching on when on electric hookup which could happen if your vehicle battery gets charged when on hook up..
    Think most of the instructions cover that possibility if wiring to a mh.
    You will need a side light feed to the control box as well to dim them when you turn on the normal lighting...
    I avoided using a feed directly from the vehicle wiring and chose to use a relay activated by an engine run signal. The power to the relay been taken from the transit aux battery...
    Can't think of much else... hope it helps

    There shouldn't be a canbus issue if you take the power supply from say the cigar lighter feed, assuming it only works with the ignition/engine running.

    The ones and zeros remark was a reference to the canbus being effectively a digital network which controls where power goes to, for example the indicator stalk sends a signal to a controller which turns on the indicator light. A light cluster thus might only have two wires going to it, one thick one carrying the power and a thin one carrying the digital signals. It can be done with just one wire if the signals are overlaid on the power supply as a pulse.

    From memory the system was developed for aircraft as there was a significant weight saving to be gained by removing the need for looms with a gazillion wires. Military aircraft typically use fibre optic cable for the signal so they are impervious to the electromagnetic pulse of atomic bombs. :eek:

    You take the feeds from where the instructions say. No faffing with cigarette lighter supplies. Takes no time at all and all under the bonnet.

    They certainly look the biz Techno !!
    Had mine 18 months ago from LEDSRUS whilst at the Malvern Show. They are really good looking at a penny under £50. Believe me, if I can fit them, then anyone can....a peace of p... !!

    Ledcom ones are very good not the cheapest, I had some on my last van. They wire straight into the fuse box by-passing the CANBUS and a relay connects to the side lights so they turn off when lights turned on.

    Fitted these to my Burstner, a mate wired them in it was easy for him. They come on with ignition and automatically dim when you put side or main lights on. Each on is individual so you can put them to whatever shape you like or how many you want. Can't remember who I got them from now but we're about £70

    Why not just switch on the sidelights?

    You have to think/remember to do that. DRl's come on when key is turned & go off/dim when lights are turned on.

    In my opinion to have them is to be seen or more chance of it anyway. Volvo have been doing it for years it's not a new thing. And I think all vehicles are now fitted with them as standard.

    i really don't get day driving lights, pretty sure even in Britain that big ball of hydrogen in the sky gives off plenty of light, if not put side lights on, at least they have rear lights.
