Triumph is kind enough to pre-drill a couple of holes near the
bottom of the fender, under the license plate bracket. I'm
not sure what they're for, possibly some other country's license
plate style, but the hole on the left worked great as a
pass-through for the LED's wiring harness.
I then fed the wiring harness up along the existing Triumph
harness that powers the license plate light and the brake
lights. You can feed the LED's harness up onto the wiring
harness holder clips that Triumph has placed under the fender.
This photo was taken at a low angle, but when you're standing up
next to the bike, you really don't notice the wiring harness, as
it kind of disappears under the angle of the plate.
This is a photo looking towards the back of the bike, at the
back of the license plate.
The pink arrow is pointing to a
fender washer -- I bought a couple of these at the local
hardware store to back up the through-bolt from the LED that
also holds the plate to the mounting bracket.
that came with the LED were kind of small, and I wanted a good
backing to make sure the nuts didn't pull through.
I also found some rubber washers and put a couple of those on for
good measure. It makes for a pretty solid installation, even
though the bolts shown here are only about 1/8", rather than
the typical 1/4"-20's used for mounting license plates.
I could have used the larger bolts, but that would have meant
drilling out the Triumph's mounting bracket, and I didn't want to
