Headlight relay kits that are essentially plug and play. There is a substantial increase in voltage at the headlight, increasing light output performance. Light output degrades exponentially with voltage input reductions. These kits also take headlight amp loads off the fragile bulkhead connector, headlight switch and amp gauge. The only headlight load flowing through the bulkhead is a minimal current required to trigger relays. The kit includes: Bosch/Tyco relays (no 1$ chinese relays) Ceramic headlamp sockets Fuses/fuse holders 12ga wire from alt to relays 12 or 14 gauge power wire from relays to headlight wiring (no 16-18 gauge wire like factory, except 16ga to trigger relays) All terminals for hook up to a std 1/4 alt stud and ground locations Wiring would follow normal wiring harness paths and be covered with black shrink tube for most of the run lengths. ------------------------------------------------------------------------- NO CUTTING OF YOUR CURRENT WIRING HARNESS REQUIRED! Road lamp relay kit is not included in the standard 2 and 4 headlight kits. There is an additional charge for a road lamp relay kit. The kits I've built have relays mounted on the yoke (front or rear), under the battery tray and inner fender uprights. Picture of the light output difference from a 71 Cuda. Both pictures are on low beam setting, Left - before, Right - after installation. Another benefit that most users see are an improvement in dash light and marker light/turn signal brightness. Some other things to consider. Unless you buy wire in bulk, you'll have about $40+ before tax in different colored wire packages from a local auto store. All kits I build are tested prior to shipping. Kits for a 2 headlight vehicles are $135 + shipping. Most 4 headlight vehicles are $160 + shipping. The assembled kits fit nicely in a USPS flat rate box, shipping in the US would be in the $10-15 range. International shipping is available. Kits have been shipped to Canada, Spain, Italy, Germany, Australia, New Zealand and a few other countries. Most all shipping is done via US Postal Service unless other service is requested. Kits with all products and wire required to build one yourself are $85 for a 2 headlight and $100 for a 4 headlight + shipping. If you would like some other iteration of a kit, parts only, please PM me. All items are shipped from Indio, CA Thanks to all my customers, I appreciate your patronage!
