Nilight Spare Tire Brake Light for Jeep Wrangler 2007-2018 - Bright

In this review of the Nilight Spare Tire Brake Light, the bottom line is simple: this is a practical upgrade for Jeep Wrangler owners who want a brighter, cleaner-looking rear and a third brake light integrated into the spare wheel. It is aimed at Wrangler JK and JKU owners with 16 to 20 in rims and common 5-lug patterns who want immediate, visible braking signals from a high-mounted location. Installation is straightforward for mechanically inclined owners, and the unit's 85 LEDs deliver a clearly noticeable red brake signal when working correctly.

Key Features

• Third Brake Light Function: Provides a high-mounted brake signal that increases rear visibility and communicates braking more clearly to following drivers.
• Wide Fitment: Fits Jeep Wrangler 2007-2018 JK and JKU models with 16 to 20 in rim diameter and common 5x5, 5x4.5, 5x5.5 lug patterns, covering most stock and many aftermarket spare setups.
• High LED Count: Uses 85 LEDs to produce a bright red output that creates an immediate and obvious brake warning when illuminated.
• Durable Construction: Built with an ABS plastic frame and IP67 waterproofing to resist road moisture and light off-road exposure.
• Long Lifespan: LED lifespan rated over 30,000 hours for long-term service without frequent replacements.
• Simple Hardware Fit: Mounts onto the spare tire studs so it sits flush with the spare and keeps the rear profile tidy once installed.

Who It's For

This product is for Jeep Wrangler owners (model years 2007 to 2018) who carry a rear spare and want an integrated high mount brake light that enhances safety and appearance. It suits those comfortable routing a positive and negative wire to the vehicle third brake light circuit and re-installing the spare tire over the unit.

It is less ideal for buyers who expect a fully plug-and-play wiring harness or a guaranteed perfect fit for every aftermarket spare mount; a small number of owners reported wiring or partial LED failures, so those who need factory-style plug-in reliability or who lack basic wiring skills may want to consider professional installation or an alternative solution.
