Truck-Lite 44556R – Super 44 Series 4" Round Red/Clear 8-Diode LED Stop / Turn / Tail & Integrated Back-Up Light (Grommet Mount, Hardwired Fit 'N Forget S.S. 12V)
Simplify your vehicle’s rear lighting layout without compromising on safety with the Truck-Lite 44556R Super 44 Series 4" Round LED Combination Stop/Turn/Tail & Integrated Back-Up Light. Combining both rear signaling and reverse functions into a single 4" round lamp, the 44556R replaces two separate lighting units—saving valuable rear crossmember space, streamlining harness wiring, and reducing inventory costs.
Engineered to drop into standard 4" round rubber mounting grommets, this 8-diode combination light fully satisfies federal FMVSS regulations requiring at least $75\text{ cm}^2$ of luminous red area for rear signaling. Featuring a low-profile hardwired lead that terminates in a Fit 'N Forget S.S. plug interface, the 44556R provides superior defense against moisture intrusion, road salts, and continuous heavy vehicle vibration.
