Lighting

Our vehicle lighting covers replacement LED headlight and fog-light bulbs, plus lighting for added visibility and accents. We help drivers match a bulb to its socket, installation location and intended use.

Match LED Bulbs to the Factory Socket

Start with the bulb code printed on the old bulb or shown in your vehicle manual. Codes such as H11, H4 and 9012 refer to different bases and connections. Choose the matching code, then compare the bulb body and driver dimensions with the space behind the housing. Our Lucas Lighting L3-H11, L3-H4 and L3-9012 are LED headlight and fog-light bulb pairs. For a D-series replacement, see the Lucas Lighting L3-D1/D2/D3/D4. Match the exact socket code; similar-looking bases can still connect differently.

Plan for Beam Pattern and Installation Space

An LED bulb needs to sit correctly in the housing to direct light down the road. Keep its emitter orientation aligned as the bulb design requires, and aim the lamps after installation. A poor beam pattern can reduce useful visibility and send glare toward oncoming drivers. Check room for the bulb body, wiring and any driver behind the housing. Make sure the dust cover can close without pinching wires or pressing against the bulb.

• Socket: Match the factory bulb code, including any suffix.
• Connection: Compare plug shape and wiring access before removing the original bulb.
• Power: Confirm the bulb's supply voltage matches the vehicle system.
• Location: Choose a product suited to headlight, fog-light or auxiliary use.

Choose Lighting for the Job

Headlights need a controlled road beam. Fog lights sit lower and serve a different purpose, while accent lighting adds visibility or appearance. Light bars are a separate choice for auxiliary illumination, with mounting location, wiring and exposure all part of the plan. Use each product only where its intended use and exposure rating suit the installation.

For added front-end illumination, explore exterior lighting and offroad lighting. For a bar-style setup, see our light bars.
