DIY Motorcycle Hazard Lights

DIY Motorcycle Hazard Lights

by Elmo37

Hazard light is used to signal the driver on your tail that the road ahead is dangerous or slippery. You can also use it to increase visibility on low visibility situation like rains and foggy roads. This is very useful to group of riders travelling in convoy to avoid being lost in the pact specially on low visibility roads.

MATERIALS

DPDT Switch (double pole double throw): P15

12v Flasher Relay (2 terminals): P85

Wires: free

1/2'' X 2" Metal Sheet: free

Total : P100

EQUIPMENTS

Soldering Iron/Soldering Lead

Electric Drill

Electric Tape

*note

test your stock flasher relay first if it can handle the job, if not buy flasher relay that has higher capacity preferably 6 bulbs.

Solder 1-2 feet long wire (depending on your set-up) to pin 1, another wire to pin 2 then attach the 3rd wire to shorted pins 3 and 4 of the DPDT switch.

It should look like this (in my set-up I used an old audio/video jack with 3 wires attached together)

To make a bracket for the switch, i drill 2 holes on a small stainless sheet (about 1/2" X 2")

Folded it and attached to the screw near the signal switch.

You can place the switch anywhere you want,but i prefer to place it near other switches.

Use electrical tape to cover the back of the switch to avoid being grounded.

Replace the stock flasher relay.

Tap the wire soldered to pin 1 to the green wire connected to right signal light and tap the wire soldered to pin 2 to the brown wire connected to left signal light.(if you open the head light assembly you will see a pair of green and brown wires with plastic covering)

Tap the wire soldered to shorted pin 3-4 to the brown/white wire connected to the flasher relay.

To test,switch your key to on, signal lights should be in off position and turn on your hazard light. Turn off the hazard light if you want to use signal lights.
