Scratch this - On November 24th I received a recall notice from Diode Dynamics dated November 6th. It seems the LED headlamps they sold me that fit the Buick Envision that were supposed to be street legal do not meet the National Highway Traffic and Motor Vehicle Safety Act standards. Thus, they are offering, get this, halogen replacements for the LED's they sold me for $150. See a copy of the recall letter attached. I told them I do not think that is a fair swap, cheap halogens for $150 LED's and am writing the Director of the NHTSA and Honorable Senator Cory Booker for starters on why the NHTSA is not making Diode Dynamics refund customer who return the bulbs. The letter size saved as a pdf is bigger than this site allows you to upload but I was able to snip the pdf and save it as a jpg and clipped it in below: 'Important Safety Recall #20E-077'
I also snipped a portion of the email order confirmation I received, note the words..."Bulb Model: SL1 (1630 lumens, Street Legal Output)"
I am not willing to accept a pair of inexpensive Halogens when I paid $150 for their Street Legal Output LED's.
