Here is 6k I know you want 4 or 5k but quality is amazing from DD XLM2 so you'll be making a good choice if you want to just replace the bulb

OK, so a follow up to my review:

I have had some issues with these lights.

First, the metal cap on the end of one of my lights came detached and is sitting in the foglight housing. Make sure yours is tight before you install.

I have had both lights fail. In both cases, the LEDs themselves burned out. Symptoms were an electrical sounding noise emanating from the bulbs for a period of time, then they failed.

Diode Dynamics has been very good about shipping replacements. I plan to replace the latest failed light and get the cap out of the housing this weekend. Will be the fist time I've had the bumper off of this car.

I had the same issue with burned out LEDs. Mine happened to both side simultaneously. It lasted exactly 1 year, but DD made good on their warranty and sent me brand new ones for replacement.

Great customer service but hopefully better quality control.

Same experience exactly.

Yeah.

At this point, I have replaced both sides multiple times. All appear to have been the LED unit burning out.

I contacted DD to inquire about a refund, as I did not want to get 10 times the product I originally paid for via returns. They said I was out of the refund time window and sent me yet another replacement bulb. How they can stay in business like that is beyond me, but I appreciate the support. I suspect they would cut me off at some point.

For now, I have some new Retrofitsource units I will be trying. I will post my results for everyone.

I can now say without hesitation that you should NOT purchase the Diode Dynamics LED bulbs. Instead, go for the RetrofitSource H11 Morimoto 2Stroke LED bulbs:

These bulbs are a much better design, with extended cooling plates. They give off the same clear white light as the DD units, but last longer. I have had mine in place for 4+ months with NO issues whatsoever.

I certainly wish I could recommend the DD units, and I have absolutely no issues with the Customer Service I received from them, but nothing is a substitute for quality product, which the TRS units most certainly are.

I hope this helps.
