Buying Guide

Match the socket type

Confirm your vehicle's bulb socket (e.g., 912/921, 3157/3156, 9007) to avoid fitment and electrical compatibility issues

Check lumen output and LED type

Higher lumen counts and modern chips like CSP or SMD yield brighter, more consistent light; AUXITO's 4000-lumen CSP example shows the kind of spec to compare

Consider color temperature

Cool white (~6000K–6500K) improves visibility for backup lights, while amber or switchback options are needed for turn-signal/dual-color applications

Look for projector or lens optics

Projector lenses or directed optics (as used in some SEALIGHT models) help control beam pattern and reduce glare to other drivers

Confirm CANbus or error-free features

Vehicles with bulb monitoring require CANbus-ready bulbs or resistors to prevent dashboard errors and hyper-flashing with LED replacements
