I'm tempted to try out the Halo LED headlights on Amazon for $120 ish.

$63 for speaker upgrades, I can't recommend it enough. I got 2 kits for both soundbar and front speakers, took me less than 2 hours to install it all myself.

Next on my wish list is the switch panel that goes on the windshield, hook all your lights into one unit.
