Most modern cars today use a system to continuously detect faults – known as CAN-Bus. These bulbs are CAN-Bus enabled and will eliminate those annoying warning lights when your car thinks it has a faulty bulb.

Cree is the Rolls Royce of LED technology recognised the world over. Most major manufacturers of LED products use Cree LEDs. This particular bulb uses 6 Cree LEDs and gives off 360 degrees of light.

Although your vehicle battery is used for all the electrics any saving in power has to be a good thing. These bulbs will give a greater light output (750 Lumens) than the standard bulb (300-400 Lumens) but use much less power - a win win!

One of the many advantages with LED bulbs over the standard is the length of time they will last. LED bulbs will significantly outperform standard replacement bulbs and should give 4000 hours or more of trouble free use. Unlike some other more inferior LEDs the light output with a Cree LED will not deteriorate over time.

We are so confident with this range that we offer a full no quibble 3 year guarantee....

Understanding CANbus Error Codes And How To Fix Them

I bought these with the ABD resistor kit and they don't work together on a Volvo V70 without bringing on the bulb failure warning message and the indicator going about twice as fast as it should. So far the red Twenty20 Cree LED bulbs don't work either on this car so I would ignore the little ABD video and do your own research as to what works on your particular car, especially if it's a Volvo.

Advantages: Bulbs are bright and give good colour through the lens.
Straightforward fitting.

Disadvantages: Flash way too fast.
Brings on the 'Bulb Failure' warning message, even with the ABD resistor kit fitted.


Our Reply: Please note the ABD resistor kit is a 10W resistor and may not always be compatible with a 21W application such as indicators or break lights. In this instance, we would recommend using the 21W resistor kit by Osram as described in the video.

Great light output but could be better if the flash rate wasn’t so badly affected

Advantages: Significantly brighter for thos sunny days

Disadvantages: Needs external resistors to correct the flash rate. Why can’t these be integrated by the manufacturer?

Our Reply: Resistors are included as part of the bulb but it's still not the same resistance as a standard bulb as a major benefit of LED is the lower power draw.

Hyper flashing on LED indicators can also be fixed with LED flasher relays that are available on our website.

I ordered these bulbs using the car registration finder but unfortunately they weren’t compatible with my car, despite fitting and illuminating they gave dash screen errors and hyper-flashed.

A quick email to ABD and they offered a full refund with free return postage so although the bulbs themselves weren’t correct, the customer service was excellent.

Advantages: Very bright and look discreet in clear lenses.

Long life and warranty.

Disadvantages: Unfortunately, incompatible with my ST 3 without fitting a resistor kit which sort of defeats the object of expensive plug and play bulbs.

Our Reply: Unfortunately some vehicles still evade even the latest canbus compatible technology. In this instance adding resistors or fitting an LED flasher relay would resolve the issue.

I bought 4 of these to replace all the indicator bulbs on my car., for extra brightness next to the headlights and for longevity.
Worked perfectly in the front, but in the rear, even though Canbus type, triggered the backup system in the C-Class and did not function.
Had very helpful email discussions with ABD, who suggested alternatives, but decided it was simpler to return the pair planned for the rear. No problem with ABD and the return process was simple and the refund prompt


Advantages: Easy to fit and bright for when indicators are closely adjacent to the headlights.

Disadvantages: ALthough Canbus type did not work in the rear indicators.
