SUPAREE Spare Tire Brake Light for Wrangler JK JKU YJ TJ - Plug & Play

In this review the SUPAREE spare tire brake light is evaluated for Jeep Wrangler owners who want a brighter, plug-and-play third brake light without modifying the vehicle. The single biggest reason to consider this unit is its ease of installation: the kit is designed to be plug & play for 2007-2018 JK and related models, avoiding drilling or wire cutting while delivering a clearer, more visible red brake signal from the spare tire area.

Key Features

• Plug & Play: Installation requires no drilling or wire cutting, which makes fitting the light fast and reversible for most Wrangler owners.
• Model Compatibility: Designed to fit 2007-2018 JK, JKU, YJ and TJ models with 16 to 20 in rim diameters and common 5x5, 5x4.5 and 5x5.5 lug patterns.
• High Brightness: The assembly uses 85 LEDs to create a strong red output that produces immediate and obvious braking warning signals visible through the spare tire.
• Durable Construction: A polypropylene mounting plate and IP67 waterproof rating mean the unit is built to resist corrosion and survive harsh weather.
• Multi-function Visibility: Lights up the inside of the spare when braking, improving rear visibility and adding an extra safety cue beyond the factory brake light.

Who It's For

This product suits Jeep Wrangler owners who want a tidy, bolt-on upgrade to the rear brake signal, especially those with factory-style spare tire mounts and 16 to 20 in wheels. It is particularly useful for drivers who value a quick install that does not require cutting vehicle wiring or modifying the body.

It is not for vehicles outside the listed model years or for owners who require a light integrated into a custom spare carrier or nonstandard lug patterns. Buyers who expect a guaranteed fault-free fit should note that a small number of users report functionality issues, so check wiring connections if problems arise.
