May I ask what CANBUS compatible bulbs are please.Legally, no.
But look to changing to LED bulbs and swapping back for the MOT.
You may need CANBUS compatible bulbs.
You wonāt have a CanBus on 21 year old van, but itās like network for cars/vansMay I ask what CANBUS compatible bulbs are please.
The idea of better nighttime visibility is appealing on a 21year old Motorhome, which seems to use Candles for illumination!
Thanks but it is a brand new van so, whilst I will check, was hoping it was setup correctly when it came out of the factory!Might sound daft but have you got the headlight adjustment turned down ?
They are the same wattage as standard builds otherwise they would be illegal and couldn't be E marked.This issue is actually exaggerated if high performance bulbs are fitted, as they are rated at higher wattage, which results in even lower voltage at the bulbs.
My take on CANBUS. It may be wrong but the principle is the same.May I ask what CANBUS compatible bulbs are please.

Interesting they give a power input and a nominal wattage which are different, looks like a bit of fudging to me.I agree Lenny, but many high performance bulbs exceed this figure. See the technical spec for Osram Night breaker Lazer. In put Wattage 68w.
Just saying.

The LED itās self will be less than 12v, it will have built in control for it so it will always see the voltage it needs.Good word that "fudging". I have found several that exceed the 55W, some by a considerable margin. I suspect that is why their life span is so short.
What I do know is the use of LEDs is enhanced by the lower wattage, enabling higher voltage at the bulbs, due to lower demand on the system. So a bit of a win-win.
It's about time some of the better conversion LEDs were approved for use.

Thank you Pappajohn for that explanation.My take on CANBUS. It may be wrong but the principle is the same.
CANBUS is a computer controlled wiring system.
Instead of a myriad of heavy wires it uses a signal wire to direct the power to wherever is selected.
If, for instance, you want rear lights, instead of a heavy wire to each bulb of each light there will be one or two heavy feed wires and a signal will be sent telling the computer which lights to send that power too.
It needs to sense resistance on that circuit and if the wrong resistance is sensed it will produce a fault code and bulb failure warning.
CANBUS LEDs have the resistance built in so won't produce a fault.
Have to say I do love the idea if travelling across the prairie in a covered wagon, a strong young woman with you facing the unknown. Somehow driving up the A1 alone in the pouring rain does not seem the same.Thank you Pappajohn for that explanation.
But yet again I notice the ultimate reliance on a central ābrainā, ie a Computer.
What happens when the Computer ā Brainā dies?
All , I suspect, is lost, in both power management and electrical functions?
And this is on an ICU based, heavy fuel vehicle.
Goodness knows what will happen on an all electric vehicle , be it a car, truck or even a Motorhome.
Think Iāll change to a Horse and covered waggon, traditional traveller style, with an open fire and a bucket for washing.
Far less complicated , but then I am a bit of a Luddite.
Errm, except me! As I explained in Drewās thread, the MoT technician invited me into the bay to see why the Katurs resulted in an MoT failure for our MH. The light pattern was all over the place.Everyone who has fitted the Katur LED have had them pass the MOT even though they are illegal including me.
Headlamps are powered by the alternator thoughBefore you go down the route of changing the bulbs check your cab battery, we had similar issues on a previous car where we changed the bulbs but it made very little difference, shortly afterwards the battery died and was replaced FOC as it was under warranty still however the recovery chap who did it put in a much better one as the original was one of the cheapest the manufacturer could get away with, the difference was immediate and the lights worked as they should have from the start, so it was either down to the battery failing or just being crap from the start.
But if the battery is crap and taking the juice it will affect the output - I'm not a mechanic, all I can state is what happened in a 'real' situation rather than a theoretical one. When driving on country roads it certainly made a heck of a difference.Headlamps are powered by the alternator though
Probably a Smart car with a PP3 battery.Headlamps are powered by the alternator though
I've always thought the standard Ducato lights aren't bad but the Hella projector lamps used in A Class vans are diabolical.
I changed our headlamp bulbs over to Osram Night Breaker Unlimited.
Although the video is testing the Osram Night Breaker Lasers, but if your look at his graphs, the Unlimited come out on top.
