LED Fog Lights Built for Low-Visibility, Low-Mount Driving Conditions

Explore Underground Lighting collection of fog lamps, fog headlamps, and auxiliary fog lights—engineered for low-mounted bumper installation to improve visibility in fog, heavy rain, snow, mist, and poor-weather night driving. Unlike low or high beams like spotlights and driving lights, fog lights use a wide, flat, short-range beam pattern designed to minimise backscatter, which is light reflecting back toward the driver.

All products in our exclusive collection are LED fog light bulbs and plug-and-play LED fog light kits, replacing halogen fog lights, which typically produce warm yellow light, run hot, and have a short lifespan. LED fog lights use solid-state semiconductor technology (p-n junction electroluminescence), eliminating filaments and gas while improving efficiency, durability, and response time, making them essential for all drivers. HID fog lights are intentionally excluded due to glare risk and over-brightness in fog conditions.

The collection supports projector fog lights (lens-based cutoff) and reflector fog lights (open housing), with controlled output optimised for fog use rather than distance illumination. Output is balanced within fog-appropriate ranges (≈700–1500 effective lumens) to prevent overbrightness, which worsens fog reflection, making LED fog lights better than headlights.

Available colour temperatures include:

  • Yellow / Amber (≈2700K–4300K) for maximum penetration and reduced glare

  • White (≈6000K) for contrast in light mist and rain

Covered fog light bulb standards include:
H1, H3, H8, H10, H11, 9006 (HB4), 880, 881, 5202, 9140, 9145, PY13W, PSX26W, supporting OEM fog light housings across cars, SUVs, and trucks. Both bulb-only replacements and complete aftermarket fog light kits are included, compatible with 12V vehicle electrical systems, factory switches, and relay-based wiring harnesses.

Why Choose Underground Lighting LED Fog Light Upgrades

  • Reduced Backscatter by Wide, Low Beam Geometry

    Fog lights are mounted low on the bumper and use a wide, flat beam pattern, reducing light reflection from fog, rain, and snow compared to low or high beams.

  • Improved Road Edge & Lane Visibility

    LED fog lights enhance illumination of lane markings, curbs, and road edges, improving vehicle orientation when forward visibility is limited.

  • Optimised Colour Temperature for Fog Penetration

    Yellow fog lights (≈2700K–4300K) penetrate moisture more effectively than white light, while white fog lights (≈6000K) improve contrast in light rain and mist.

  • Instant Full Brightness for Sudden Weather Changes

    LED fog lights reach 100% output instantly, unlike HID systems, making them effective when fog or heavy rain appears suddenly.

  • Lower Power Draw With Higher Durability

    Operating on 12V DC, LED fog lights consume less power than halogen, generate less heat, and resist vibration—ideal for daily driving and trucks.

  • Longer Service Life With Fewer Replacements

    LED fog light bulbs typically last 25,000+ hours, compared to 400–1,000 hours for halogen, reducing maintenance and replacement frequency
