Car Lighting

Car lighting upgrades promise more light, but the real questions are whether the bulb fits the housing, whether the beam pattern stays legal and glare-free, and whether the car's electronics accept the new load. LED bulbs in halogen reflector housings often scatter light into oncoming traffic. CAN bus cars flag a low-draw LED as a burned-out bulb. Light bars need a relay and a fused feed, not a splice into the headlight circuit.

The guides in this hub are grouped by that risk. Fit guides cover bulb sizes, housing types, and specific vehicle installs such as aftermarket headlight assemblies. Glare and beam guides explain how to check a cutoff line and what flicker or hyperflash means. Wiring guides cover relays, switches, and fuse taps for light bars and auxiliary lamps.

Read the featured guide first if you are choosing between LED and halogen replacements. Then use the cluster lists to find the guide for your bulb size, your vehicle, or the error message your dash is showing.

Products are linked to the seller's page with the fit information we could confirm. Lighting laws vary by region, so treat a brightness claim as a starting point and check local rules on colour and output before installing anything on a public road.
