AUXITO H3 LED Fog Light Bulbs 6500K White — Pack of 2, 300% Brighter, 1:1 Mini Plug-and-Play

The AUXITO H3 LED Fog Light Bulbs are compact, plug-and-play 6500K white LEDs designed to replace H3/H3LL halogens for brighter, longer-lasting fog, DRL, and beam lighting.

These H3 LED bulbs from AUXITO use high-density CSP chips and a mini 1:1 form factor to deliver a crisp, cool-white beam that cuts through rain, fog, and snow more effectively than stock halogen bulbs. They are built with aviation-grade aluminum for efficient heat dissipation, IP67 waterproofing for reliable performance in wet conditions, and a non-polarity design for straightforward installation on most vehicles.

How much brighter are these AUXITO H3 LEDs compared to halogen bulbs?

With 8 CSP chips per bulb and a 6500K color temperature, these LEDs produce a stronger, whiter output that appears up to 300% brighter than many factory halogen H3 bulbs. The cooler color improves contrast and visibility in low-visibility weather while keeping power draw much lower.

• 8 CSP chips for dense light output
• 6500K cool white for improved contrast
• Estimated 300% perceived brightness over halogen
• 60% lower power consumption vs older LED designs

Will the AUXITO H3 bulbs fit my car and are they easy to install?

These bulbs are designed in a 1:1 mini size to match standard H3/H3LL halogen sockets and feature a non-polarity single-wire connection for plug-and-play installation. Most vehicles accept them without modification, though a small number of cars with highly sensitive CAN bus systems may need an optional decoder to prevent error codes or flicker.

• 1:1 mini form factor for a direct physical fit
• No polarity wiring simplifies swap-in installation
• Plug-and-play on most makes and models
• Free decoder available if your vehicle needs CAN bus support

How durable are AUXITO H3 LEDs for all-weather use?

Constructed from aviation-grade aluminum and rated IP67, these bulbs shed heat efficiently and resist water and dust intrusion, making them suitable for wet and rough conditions. The thermal design and LED longevity combine to offer an expected service life up to 50,000 hours under normal operating conditions.

• Aviation aluminum body for rapid heat dissipation
• IP67 waterproof rating for rain and road spray
• Rated up to 50,000 hours of operation
• Lower heat and power draw reduce strain on fixtures

Do AUXITO H3 bulbs cause dashboard errors or flicker?

Most vehicle systems accept the AUXITO H3 LEDs without errors thanks to the bulbs’ stable electronic design and non-polarity connection. If your car triggers an error or flicker due to a sensitive CAN bus, AUXITO provides a free decoder to eliminate warnings and stabilize operation.

• Designed for 98% error-free compatibility
• Some sensitive models may require a decoder
• Contact AUXITO for a complimentary CAN bus decoder if needed
• Simple diagnostic steps included with purchase
