The next step is to create the new license plate mount bracket.
Take 3 mm (1/8 in) aluminum plate, mark it, drill necessary holes. The bracket mounting holes will be attached to the stock tail bottom holes with new longer screws I mentioned before.
Cut the bracket
Finish bracket edges
Clamp the bracket between two pieces of wood and align the bending lines with the wood brick edge
Bend the bracket with hammer carefully verifying with angle template. You will have only one chance to bend it, you can not unbend it back because the aluminum plate will be broken. I recommend you to chamfer the wood edge to increase bending radius.
Sand the bracket with 320 sandpaper, degrease the surface and cover it by VHT Flame Proof primer. I use Flame Proof paint for the bracket because it is pretty durable paint.
Paint the bracket with VHT Flame Proof black color and cure it in the oven according the instruction on the spray can. I used my kitchen oven.
Paint the tail. Do not cover the Buell paint by clear coat, it looks like clear coat dilutes the Buell paint and changes color. Once I had noticed it I covered again the tail by Buell paint over the clear coat. Give it to dry at least 24 hours.
Cut a few washers from rubber sheet and put them on the license plate bracket with the new longer screws I mentioned about before. I use 1.5 mm thickness rubber.
Put heat shrinkable tubes on the LED strip wires to protect them against rubbing in the bracket holes while vibrations.
Assemble the LED tube and put some silicone glue in the tip to protect against water.
Remove the old tail.
Install the grommet I mentioned about before in the tail hole.
This Ass couldn't be any sexier ... I was too lazy to cut the end and install LED's inside but will reconsider it over the winter while doing other bits ...
My red stays on while yellow flashes as well - there is no point to mess about with this. It is clearly visible even from far away.
To b honest, I've noticed many genuine bikes with far worse rear light than this LED's.
There is no better looking tail light in the wide world.
