If you want to brighten up the interior, switch to a hyper white 194 bulbs in the 4 overhead lights. I changed mine over and it makes a huge difference. You can use the colored LED's, but i've found it's a bit harder to read maps/directions/etc. with them. Change the fronts first and you'll see how much nicer they look and how more defined the colors on the inside are. Somone in here even rigged it up so he has colored ones run off a switch, so he is still able to use the stock lighting.>
It depends on the State/County/Country you live in on the tint question on the windshield. Usually, with a doctor statement, you can get some tinting done. Check with a trooper or law enforcement in your area.
Check around the sites and see if you can find a decal to your liking. Others on here may beable to help you on this.
