Absolute garbage. Nothing like the description or pictures. They're dimly lit blueish purple light that can barely be seen, even on a rainy and cloudy day. They are neither bright or white like advertised. I will be replacing these as soon possible. DO NOT BUY!!!!!!

I'm very frustrated with this purchase.

1. Do they fit - - - yes.
2. Do they function - - - yes
3. Are they Xenon Bright White - - - Absolutely NOT!

These LEDs have an actual color temperature that leans very heavily on the blue side, not "bright white". On my Mercedes vehicle the so called "parking" lights also function as running lights adjacent to the primary headlight when the low-beams are switched on. The factory Xenon primary headlights are in fact bright white while in contrast these replacement bulbs appear very blue and do not even remotely match the headlight color.

If you've replaced your primary headlights with higher color temperature blue-toned LEDs then these replacement parking light will likely suite your needs. If you are looking for a "bright white" replacement then these should not be purchased.

They have a color temp of about 6000k, which is a good enough match for the 5000k 56,000 lm LED headlights that I installed, much better than the yellowish stock halogen...one of which was burned out anyway. These lamps were a perfect fit and error-free in my 2001 Mercedes-Benz E320 W210. They are not as bright as the H6 halogen, but they will do fine. They are as bright as a running light,Zone where the stock H6 is as bright as a turn signal. Idid not measure current, but I'm sure they use a lot less power, which would use less battery when parking overnight with the city lights on.

Update: one of them burned out in June already, after being installed less than a month. The 100-ohm resistor near the base have up it's magic smoke. I'm going to try a different bulb, these weren't terrible bright to begin with.

The photos show some of the issues I had. They show obvious signs of overheated components. There are burn marks on the circuit board, and the one that failed got hot enough that one of the components de-soldered itself from the circuit board. LEDs typically get hot at the back end, not where the light comes out, and this circuit board was not designed to disperse that heat through a heatsink, other than the socket. The socket is insulated in the car, so cannot really disperse much heat.

Another point to notice is that the lugs on the bayonet plug are not consistent. In many applications, these are used to see the angle that the bulb sits at, and one or both of them is skewed.

As an IEEE Certified board repair technician, I could repair these to both function, possibly even adding a protective conformal costing to protect the components from environmental exposure, but I cannot overcome the overheating problem inherent in the design. They are going into the trash, because it's not worth the hassle of returning them for the $10 or so I paid.

The reason I purchased these bulbs and paid the premium is because the set is advertised at CAN BUS compatible. It worked for 3 months. Perhaps probably less than a total of 1 hour of use. One of the resistor came off (due to the heat). Although the vendor is responsive, they offered no solution and responded that it is past the 90-day warranty. Not recommended.

Not very bright and not error-free. I installed them on a white mercedes e320 (as pictured on the product page). It does not look anything as advertised and throws an error code.
