Replacing the incandescent lights with LED units.

I rode downtown
today to a truck shop, and looked at their LED tail light selection. I
already have some units attached to the back of the luggage
box, but now I'm modifying the stock lighting as well. The Virago has
a pretty weak stator, and doesn't like carrying the load of the incandescant
DRL's I installed up front, so I'm changing everything over to LED's to
significantly cut power use.
The easiest way would be to use 1157-to-LED array retrofit bulbs, but the only ones that are worth using cost a lot (ex: brake, turn). So, instead, today I bought a pretty decent, 60-LED array board mounted in a 4" round truck unit ($20). I plan to disassemble it, cut the board to the size I need, and resolder the connections as necessary. It should look pretty good, and fill the entire tail lamp.
Here's a comparison
of my Virago's rear tail lamp lense, and the 4" round LED truck stop/turn/tail
unit I bought:
The red lense is
carefully broken off, revealing the components inside:
Here the LED circuit
board is removed from the base, to examine it:
Using a dremel,
the board is cut into the smallest possible shape, without dividing the
necessary circuitry (luckily there is some redundant circuitry, so a severed
circuit doesn't necessarily mean that it needs to be resoldered). The base
of the old 4" unit is cut down to create a small pod to screw the board
back into, for support. Here's the new unit (note the screw notches on
the sides):
The new part is
fitted to the bike's wiring...
...and tried out
- works great!
