Fitting of hazard lights

[steben]

This was emailed to me when I bought my 02 VFR. Thought I would copy and post here for others to use. I would like to thank the person that documented it but have no idea where it was from.

Why don't motorcycles have hazard lights (OK, 2004+ VFR's now have them)? This one is easy. You need a two prong flasher relay from any automotive store, two diodes (NTE5812 Rectifier Diode, 6A 100V), and a switch (switch is optional). Using removable wire leads, take power from a constant wire (battery +) and attach it to one of the flasher posts. Connect another removable wire lead and wire to the other flasher post (you can hardwire this but then replacing the flasher will be a pain) and solder it to the two diodes. The diodes allow electricity to flow in only one direction, use a multi-meter to make sure the diodes are allowing current to flow from the flasher toward the turn signals. The diodes prevent the left and right turn signals from cross powering each other during normal operation. Now you have two diodes connected to one wire from the flasher. Run one diode to the left blinker wire and the other gets spliced into the right blinker wire. Splicing into the rear turn signals will energize the front as well. You can disconnect the power wire from the flasher relay and tuck the wires away under the seat (see video above) or you can run a switch between the battery and the flasher to make things a little easier to access. Be sure to use wire heat shrink wrap or electrical tape to insulate all your connections and diodes. My thought on the hazard lights were that if you are on the side of the road, you cannot leave your lights on for long without draining the battery. The hazards will give you the protection of being seen without draining the battery by running the headlights. Adding a switch and hiding it up under the dash gives you the ability to turn on the hazards when you want, rather than having to go under the seat to connect the flasher.

I also found this on the web. Not sure who, but I did it for my 4G and installed the switch in the rear, under the seat. Works as advertised!!!

Glad to hear it works, I bought everything today to do the job apart from the diodes. Cant find any in Hobart anywhere. Wanted these working before this weekend as we have a big ride coming up.
Hope I will find some soon.

Call Tightwad at www.wiremybike.com. I'm sure he can fix you up, and quickly.

Thanks for that but got talking to a guy this morning and he gave me some different spec diodes but said they will do the job.
I now have hazard lights with a waterproof switch up front. WooHoo
