Yesterday we were in Camping World in Rocklin, CA., and at the check out they had a box of 2 50-watt halogen back-up bulbs by DesignTech International, Inc. Thanks Spaceman for doing the project!!! I went to their website, and don't know what's up, but the DesignTech-Intl.com stated on the box comes up with a remote car alarm company - weird. :wacko: Any of the electrical guru's here will want to take a look at their Snake Pit page with how-to's / tutorials.
