i am using led bulbs made by "jamstrait" found at autozone. they have a "10 year warranty" they seem to be much brighter both on brake lites and parking. i have a fair digital picture of the package if it would be of help. also keep checking the webpicture site by thomas for updated pictures on the cable tools etc. http://www.corvair.de/n2vzd/ thank you thomas! regards, tim colson
