What late model accessories do you wish your old car had?

What is this ?
Crackedback builds very nice plug and play headlight relay kits. Because they get their main power from under the hood instead of through the bulkhead to the headlight switch and back through the bulkhead, the headlights are very bright and the system is a lot safer because of the reduced load.

This is the first I saw this kit. Does this system allow for the use of newer head lights with Halo lamps?
