I bought mine at FleetPride truck parts. They are a 4" SlimLine LED and were about 5.00 each.

Bama,
I'm looking for some running lights like yours. May I ask what ones you have, where you got them, and how much they were? I am looking ot do the six on each side, too. I thought of the Recon Big Rig lights just because of the ease of wiring. Here in N. Illinois, the salt and ice are a pain on hanging wires and connections. Thanks.
