great quality December 12, 2011
Reviewer: Paul Neese from Anaheim, CA United States  
Great LED bulbs with great price! Most importantly there is no error for both my Mercedes W204 C350 and Audi Q7!

For the Audi Q7, at first the LED bulb does not light up. Thanks to JDMtoy's tech support, it turns out that I need to close the truck, lock the car to allow the onboard computer to reset and after this everything works!

Works for Mercedes SLK September 12, 2011
Reviewer: Jaya from San Jose, CA United States  
I got a piece for my 2009 Mercedes R171 SLK350 for trunk area light.

This kind of error free LED bulb fits perfect and light up with no error.

I have previously purchased the much shorter 36mm  error free led bulbs but I need to squeeze the metal pins all the way inwards in order to hold the bulb, but still very loose.

This 42mm error free led bulb on the other hand has perfect fitting!
