Front air cleaner lite bars accentuate the air cleaners with mirror-like stainless steel lites. Attach to the front of air cleaners on Peterbilt 389 models. Available for both standard or premium air cleaners. In order to properly install the lite bars, check whether your air cleaner has a standard or premium can. If unsure check where the cover meets the can, if there is a flange, you have a STANDARD CAN, if it is flat with no flange, you have a PREMIUM CAN. Lites are amber, but are available in both a clear lens and amber lens.
