OSRAM LEDriving Canbus Control Unit, LEDCBCTRL102, 21 W, Avoid Error Messages in the Board Computer when Using LED Fog Lights, Folding Carton Box (2 Pieces), Gold

I bought a set of LED bulb that were advertised as Canbus Error Free but after fitting, I had the dreaded bulb failure warning. I then purchased a second set which were also advertised as Canbus Error Free but I still had the bulb warning. So after working out which Canbus Control Unit I needed for a 21w bulb, I decided to give this a try and, Hey Presto, problem solved! They are a bit fiddly to fit, making sure that the unit was screwed to metal, but the end result was worth it. I now know what to buy if I change any other bulbs to LED.

Used 5w version for number plate lights on my ducato van, each original bulb was actually 10w each, the new led say 5 w each but was not error free so I installed these, one to each light as directed in the pictured only manual ( love it) and work a treat, cheers!! bulbs now a lot brighter and can read the plate better and just looks neater and newer. Easy installation but the clamps are so small and hard to fit just just use pliers to squash together

They do the job. Although in different lighting levels (day / dust etc), the colour emitted goes from whitish, to blue tint! Not that super minty white colour we all are hoping for. Not yet found anything that meets the bill !

These worked as advertised. I was able to install OSRAM LED indicator bulbs on my car without hyperflashing. Although I think they are a bit overpriced for the job they do.

The first pair of these I had one fail within the warranty period, and despite contacing Osram several times through their preferred channels, I heard nothing back. I ended up having to buy the next set myself as Osram didn't respond to my warranty request. So my rating is for their poor customer service and shrugging off their responsibility to replace a defective unit.

Great product, highly recommend getting a professional to help.

This little thing solves the annoying issues related to retrofitting LED bulbs in the vehicle (fast flashing, bulb out warning on dash....etc) . The product quality is high and the instructions are included with a very easy to follow steps.

Ok
