    I have a Hymer B544SL and the bulbs in the driving lights have blown. In view of the known problems with the headlights shattering on these models I don't want to replace the 21watt bulbs with traditional,ones as they create a lot of heat.

    Can I just buy LED bulbs and use them as replacements or will they cause Canbus problems?

    Thanks for any advices.

    Should be ok if you use canbus error free ones.

    What are the 21watt bulbs.
    Indicator and brakelights are 21watt.

    Thanks for that. The Hymer has driving lights that come on as soon as you turn on the ignition and they are quoted as being 21 watt. Some people have replaced with a lower watt bulb to keep the heat down but I prefer an LED of equivalent power.

    They are DRL rather than driving lights. Daylight Running Lights (y):)

    changed mine last month, including losing a bulb into the housing, you really couldn't make it up

    my Mercedes chassis is 06/07 and although it has canbus the LED bulbs bought from my local motor factors do not bring up any errors, cost £5 / pair, look nice as well as not being hot

    not only do they get hot behind the glass even the bulb holders were going brown
