You could use a Harley Tombstone.
I'll leave my opinion of it out.
You will have to look real hard for a brighter light than this Valkyrie one.
This picture is taken inside a garage but look at the reflection off of the seat.
It has 132 LED's in it. That by the way is the Brake light.

I agree with RJ on the tail light. It fits, looks great and with that LED panel (I also have it).... it is VERY BRIGHT. Bend that little bracket thingy out of the way. I plan to do the Super Valk mod this winter and it will be cut off anyhow. Others have used different lights..... but a stock light also fills that hole which is covered by that little plastic piece. You can find em on Ebay now and then....
Edit... RJ... just noticed your vanity plate....
