This is a used Whelen 600 Series steady burn amber light—still fully operational, just showing a little cosmetic wear from previous use.
Whelen’s known for making tough, reliable warning lights for emergency vehicles, construction trucks, and industrial equipment, so even used, this thing’s got life left in it.

It’s the 600 model, amber/yellow color, made in the USA.
It’s a steady burn light, so it stays on constant rather than flashing—great for applications where you need visibility without the strobe effect.

It might have some scuffs or minor marks, but functionally, it works as intended.
Could be a floor model, store return, or just a take-off from a vehicle.
The MPN is simply 600.

If you need a spare, a replacement, or just a budget light for a project, this is a solid pick.

Whelen parts are built to last, so even used they’re often better than cheap new imports.

Perfect for tow trucks, farm equipment, or off-road rigs that need a little extra visibility.

Test it when you get it, and if it lights up, you’re good to go.
