don't buy C6 LED for your handlight, i got from ebay and seller don't care about you waste your money and time, finally i need ask for credit card give me money back
"Hey everyone, I just tried out this white LED headlight. My old car originally used those traditional yellow bulbs, so I decided to switch them all out for these LEDs.
However, if you're thinking about upgrading your headlights, please do not buy this brand called 'C6.' Seriously, stay away from it. I used them for less than two weeks before they burnt out. They are extremely unstable.
I bought mine from an eBay store, and I'm sure they're available on other websites too, but based on my experience, I absolutely do not recommend them. Unless you enjoy wasting your time and money, don't buy this brand—get something else instead.
Even though this model comes with a built-in cooling fan, it clearly doesn't do the job. After about two weeks, the light became very dim. I did some research online and it seems like the fan and the heat sink are just poor quality.
Alright, that's it for now. Just wanted to give you guys a heads-up!"
