When it comes to lighting, I avoid Amazon and eBay unless its coming from a reputable and well known seller in the lighting business. These kits and stuff that they sell for $30 are a rip off. I'm all for saving money but don't skimp on quality especially LED headlights when it not only affects your driving abilities but others as well. It's all about safety. You'll end up spending just as much to replace the bulbs multiple times than purchasing a quality product.
I've seen people buy $10 LED brake lights or blinkers and they're barely visible during the night. Imagine trying to see them during the day? It's an accident waiting to happen.
But back to LED headlights, I was never a huge fan of them. Only because of safety reasons. I always preferred a legit retrofit. But it can be costly but the output is superb. But through the years, LED bulbs for headlights have improved drastically. My Philips 5000k Halogen bulbs recently blew and I needed new bulbs. I was going to get VLEDS Micro Evolution LED bulbs for $175 but it was too costly (my whole interior, taillight and signals are fitted with VLEDS to the price of ~$350 in bulbs). I also started to research reputable site that deal with LEDs and went to TheRetrofitSource (TRS) and they were selling the Morimoto 2Stroke 2.0 for $120. Very reasonable price but even at $120, it was a little hard to swallow. Morimoto is a very good brand in the retrofitting scene. I was about to buy from them with a coupon code that dropped it to $108 but decided to check eBay. Found a reputable seller (lightwerkz) and purchased it lower than their asking price of $120 and lower than from TRS with the coupon code. Lightwerkz is popular in the retrofitting scene so I know I was in good hands and getting a legit product.
Got it in the mail in 2 days and I must say, I'm impressed with the light output from the Morimoto 2Stroke. Came with H11 harness and it was all plug and play. Brighter than my Philips that I had and it will last a lot longer (this was my second set of bulbs in less than 5 years). Only thing is that the bulb's fan produces a noticeable fan noise when on. It's expected. I'm tempted to buy another set and installing it on my fog lights (currently using the original OEM bulbs - 3300K yellowish look...ewww). Since I'm in no rush, I'll wait for the next sale or big discount code.
