I'm installing aftermarket headlamp assemblies in my wife's (W208) 2003 CLK 320 Cab, and they have halo lights. Can any one tell me where I can find switched 12V power (on when the key is on, off when the key is off) that I can use to power the halo lights?

Thanks,

I used the cigar lighter fuse (#23), with a "Tapa-Circuit" from NAPA. This made it really easy, as that fuse is in the main fuse box under the hood.
