I have modified her spyder SE5 rear l/p reflector with LED pucks. I did the same thing with the reflector on my GL1800 a while ago. I could use the $10 per unit puck, 2 required, on the wing because their intensity equaled the running lights. I point this out because...
I had to use the $20 per unit 1.25", 2 required, on the spyder because I had changed all the rear to the high powered LEDs from NMN. I think it looks better with all the lights on the rear being of equal brightness. I also used the 3 wire which has low, high and ground. Low for running light and high for brake light. I am using a temp set of 1 inch super white... you do not want to use super white through the red lens. It looks orange/pink. I have a set of red enroute which should be here tomorrow.
I used a dremel to cut to round holes in the black plastic in the box. Exercise caution to do this part of the task. You do not want to damage the red lens. It is a good idea to leave a strip of black plastic from the top of the fixture to the bottom where the screw hole is, I left about a 5/8" width, this will re-inforce the red lens to prevent it from cracking.
I wanted to take it out but I could not get the glue/sealant to release. I soaked it in alcohol but that did not help. It also appears to have a snap in lip molded on the black plastic.
Since I was running a dual circuit puck I ran three 16 ga wires, red, black, green, in spiral wrap using the same general path as the l/p bulb wires. You could use 18 ga with the LEDs because of low current draw. I had 16 ga available at the time. If you are changing the l/p bulb to a LED at the same time and only want a running light you can use the same wires as the plate light and a less expensive LED puck. I never want to over load a circuit and I want both brake and running so I ran new wires for this purpose.
For running light and l/p light only use just one of the super bright red pucks in lieu of the light plate bulb.... cut the round holes in the black plastic. This will light the plate and put light out of the two holes. I tried this but it looked unbalanced so I went the 3 light system.
I change most of my small battery systems to LEDs to lighten the loads on the battery and charging systems. It also adds a much brighter, chrisper brake light and turn signals.
If anyone needs any other information that I might have let me know. This site has helped me many times :2thumbs: and I want to reciprocate.
