The AEV CHMSL (Center High-Mount Stop Light) is a must-have accessory for anyone who's using a larger-than-stock spare tire on their carrier. Many times, an oversized spare will block or even require the deletion of the factory brake light. The CHMSL has been designed for use with all AEV wheels and most factory five spokes. Super bright, long lasting LED's are aimed in three directions to provide maximum safety and visibility both on the road and off.
