For you guys that have the 2500's and 3500's and a bigger paycheck than my department provides, you should check these out! I really wanted these for my 07 mega cab but never had the extra cash. They look just like amber LED clearance lights but with the flip of a switch they strobe red and/or blue. Pretty awesome way to hide emergency lights! There are some vids on youtube as well just search for atomic led first responder.
