1. Slim: Love 'em. Great group buy!
Also, need to brace the bumper so they don't vibrate as much. I am thinking of using some aluminum strip to brace the bumber a little (bottom of bumber to cross frame. Will put up a pic when done.
2. Worth it to me. The lights are bright. I live in a dark area and good lights are necessary. The driving lights are bright enough that you wouldn't need headlights (if it was legal). They have a sharply defined beam that, if aimed correctly, won't blind other drivers, but they still light the road up.
FWIW, I've always put auxiliary lights on my cars. I usually buy the $20-$40 dollar sets. The fit, finish, and hardware you get with the PIAA is muuch better. The wires have heavy duty connectors. The wires are run in a white cover/harness. You get relay, LED switch. While I did't use the harness and relay, these are really quality units and worth the money.
The only problem with them is that your headlights seem yellow in comparison. Working on that as we speak.
