Your words.... According to aftermarket vendors such as Diode Dynamics, they had to discontinue offering LED/HID conversion kits for headlight use due to the crackdown from the DOT.
This is not true. They offer them for several vehicles. The ones recalled were, again for glare and ONLY a specific bulb size.
Actually, it is in fact very true. At this point, you haven't provided any documentation such as links from the Diode Dynamics website to back up any of your claims. On the other hand, I've provided links from the Diode Dynamics website time and time again as documented proof. Therefore, I was in fact correct about DD having to discontinue selling LED/HID conversion kits for headlight use due to DOT regulations. That being said, not my words, but rather straight from the horse's mouth!

Street Use of LED Bulbs
Diode Dynamics is suspending the sale of LED Headlight bulbs in the United States, due to federal regulations which restrict the use of replaceable light sources in headlamps. This restriction applies to all LED Headlight bulbs on the market. It is not unique to Diode Dynamics.
Our LED Headlight bulbs were designed and tested for effective photometric output, providing increased output with compliant beam patterns when installed in specific applications. However, the federal regulations do not include any provision for LED replacement headlamp bulbs. Therefore, it is not currently possible to certify any LED bulb for headlamp use.
The regulations are updated very rarely, with the last major revision occurring in 2007. However, we maintain hope that progress will be made so that advances in technology may be accommodated in the future. Newer technologies like LED lighting offer many potential benefits to consumers, which we believe should be incorporated into the regulations.
We apologize for any disappointment or frustration, and hope you will be able to find an alternate solution for your headlight needs. We are pleased to continue offering bulbs for other applications on your vehicle, as well as our highly-rated lamps and offroad lighting products. Thank you for your understanding and support.
International customers may continue to find LED Headlight bulbs available in their market, based on local laws and regulations.
