Will this replace my stock third brake light without modifications?

• ABS construction resists impact and UV fading
• Foam-mounted back plus gasket minimizes water ingress

Why choose an LED third brake light over the original bulb-style unit?

LEDs offer faster illumination and longer service life compared with incandescent bulbs, while consuming less power. The modern LED array also provides more uniform brightness across the lens and reduces the need for frequent bulb replacements.

• Quicker light-up time versus filament bulbs
• Lower power draw and improved longevity
• More consistent light distribution for a clearer signal
• Chrome housing and red lens update appearance while retaining classic looks
