These kits are all about making sure your bulbs get full battery voltage for a brighter light, and protecting your expensive lighting switches. A lot of modern bikes with Non-H4 bulbs still do not have relays to provide full voltage and protect the switches.
Due to the number of different bulbs now used, and the type of sockets these bulbs use, it’s not possible to provide a simple plug in type of relay kit such as the H4 kit. However, with the use of Posi-Lock connectors, anyone can install these Kits by following my step by step instructions for identifying your wires and making great connections.
The kits can be removed at a later time, and the bike’s stock wiring easily reconnected using the Posi-Locks, however you should consider this a permanent improvement to the bike. The kit comes complete with everything you need. You will only need a few simple tools which you likely already have, to install these kits.
Relay kits work fine with headlight modulators!
I have created a new Kit for those doing H4 Conversions to Non-H4 bulbs.
