I found these on Mikes affordable's website for 29.95. Not sure if they are the same bulbs.
I found these after I ordered the Quartz adapter kit from Snyders for $97. I had to go with a alternator to run these. Another expense that could have been saved if the LED's work.
I will wait to hear from you guys as you experiment more with them.
