You have a choice of halogen (H4, IIRC) or you can get HIDs.
The switch will be below and to the left of the steering column.
Roll the glass down because the glass comes out with the panel.
because i want a change a truck and i want t660 kenworth
It's 3 lbs, 12 ounces for the T660, and that's what it should be for the T600, as well.
Peterbilt never made the T600. The T600 was built by Kenworth, and it ended production in 2007, at which point it was replaced in production by the T660.
On Kenworth's website: (http://www.kenworth.com/3100_sea.asp), there is a truck locater. Type in your address to find Kenworth trucks and dealerships in your area!
Left side of the truck, under the hood, against the firewall is where you'll find fuses primarily for the chassis nodes. Behind the clutch pedal is the primary fuse panel, both for the cab and sleeper.
Plenty of them do. Swift Transportation has some T2000s, T600s, T660s, and W900Ls in their fleet. Navajo Expresses primarily uses the T660, T700, and T680. Stevens Transport uses the T2000, T660, T700, and I think the T680. Werner Enterprises runs some T660s. Western Distribution runs a lot of Kenworths. Just the ones I could think of off the top of my head.
Open the hood, and it should be on the right side, encased in a hinged plastic cover. IIRC, the W900, T600, and T660 all use the same cabin air filter, which can be simply washed out and reused.
most headlights are made out of a polycarbonate
Kenworth was created in 1923.
Kenworth, without a doubt.
