Nighthhawk Flasher Relay MOD
Since the stock flasher on my NH would not work correctly with LEDs,
I was forced to come up with a new flasher that would, the following is
how I did it.
First I went to Advanced Auto Parts and bought a $12 Electronic Flasher
that supports Variable Load, this will allow it to flash no matter what
draw the bulbs you use, unlike the stock flasher. My old flasher had 3
connectors, so I got the 3 connector replacement, you need to check
yours and see if it has 2 or 3 connectors, then buy the proper
The new flasher has small connectors, so, I found these gold plated
audio crimps that would work well for $4 in Advanced Auto Parts while I
I did not want to cut the stock plug off, and I couldn't find the small
male connectors, so, I used these connectors and cut half of them off
with wire cutters, they fit in the stock connector well like this.
I used a bit of wire and made my conversion wires to go from the stock
connector plug to the new flasher.
I sanded around the seam of the new flasher and used a hot glue gun to
seal it, this part is made to be inside a car/truck and probably
wouldn't enjoy getting wet, so, I sealed it up to make sure if any water
got on it it would not get shorted out.
Here is the old flasher unit, it is on the right side of the bike a few
inches behind the shock.
Here it is pulled out.
And the connector after I pulled the flasher off.
I have now plugged the new flasher in using my conversion wires.
I used a hot glue gun to protect and hold the conversion wires onto the
stock connector plug, and I used liquid wire tape to protect the
connectors I plugged onto the new flasher unit.
I then wrapped the stock connector and the wires with electrical tape.
Here is the finished job. The LEDs work great now.
I hope this helps anyone else that may be considering switching to LED
