If you want economy pricing, strobesnmore offers their own inhouse brand. Honestly, at least in my opinion, the triple threat dash lights cannot be beat. They also have the dual threat now that is a bit smaller, but why not pay just a touch more for the three headed version. The triple threat moves traffic to the front by itself. Also, if you're in the market for an ILB, their inhouse ILB uses the same heads/optics, so it will obviously move people. Several hundreds cheaper than big 3 prices. Their grill, HAWs, and others are also quite good, and again, cheaper than big names
I'm still a big proponent of Feniex. Still quite cheaper than Whelen, Fed Sid, and other big named players. Several guys on my vollie dept and guys on county sheriff run Feniex. All problems that came up were quickly handled by Feniex and the distributors they went to, free of charge.
Also, you could just hunt on here for big 3 company lights and get them at hella good prices.
