How to ensure these Auxbeam LED bulbs fit my car?

Check your vehicle's owner's manual or current bulb for the T20 7443, 7440, 7441, or W21/5W base code. These Auxbeam bulbs are designed for these specific sockets. If your vehicle is sensitive and shows hyper-flashing or error codes, you may need to purchase additional resistors separately.

Are these LED bulbs brighter than my car's original halogen bulbs?

Yes, these Auxbeam LED bulbs produce 4000 lumens per pair, which is significantly brighter than most standard halogen turn signal bulbs. This enhanced brightness improves visibility for your signals, increasing safety on the road.

What is the color temperature and beam pattern of these bulbs?

These bulbs emit a 3500K Amber Yellow light, providing a distinct and visible signal. They feature a 360-degree beam angle with projector lenses to maximize light output and ensure a wide, effective beam pattern for signaling.

Will these LED bulbs work in India's climate?

The bulbs feature a full aluminum housing designed for efficient heat dissipation, contributing to their long lifespan of up to 30,000 hours. This construction helps them perform reliably even in the warmer Indian climate.

Do I need resistors for these LED bulbs?

While many vehicles install these LED bulbs plug-and-play, some sensitive car models, such as certain GMC, Chevrolet Silverado, or Ram vehicles, may require additional resistors to prevent hyper-flashing or dashboard error messages. Check your vehicle's compatibility if unsure.

What is the lifespan of these LED bulbs?

These Auxbeam LED bulbs are rated for an operational life of up to 30,000 hours, which is substantially longer than traditional halogen bulbs, meaning fewer replacements and consistent performance over time.

Why choose this product

Superior Brightness & Longevity

These Auxbeam LED bulbs deliver a powerful 4000 lumens of 3500K amber light, far exceeding standard halogen output for critical signaling. The advanced 3030-SMD chipsets and 360-degree beam angle ensure optimal light distribution. Built with full aluminum housing and a constant current IC driver, they dissipate heat effectively, leading to an impressive lifespan of up to 30,000 hours. This means fewer replacements and consistent performance, even in the demanding Indian climate. Imported from authorized US retailers, they offer a reliable upgrade for your vehicle's safety and aesthetics.

Who Should Buy & Who Should Skip

Ideal for car owners seeking brighter, more visible turn signals and a modern amber glow. If your vehicle uses T20 7443, 7440, or 7441 sockets and you want to upgrade from dim halogen bulbs, these are a great choice. They are suitable for most 12V passenger cars and SUVs. However, if your vehicle is known for strict CANbus systems (like some GMC, Chevrolet Silverado, or Ram models) and you're not prepared to install additional resistors, or if your car requires a different bulb base type (e.g., H4, H7), these bulbs may not be a direct fit without modification.

How to use

Confirm Socket Compatibility — Check your vehicle's owner's manual or current bulb to verify it uses a T20 7443, 7440, 7441, or W21/5W base. Ensure the 12V voltage matches your car's system.
Install the LED Bulbs — Carefully remove the old bulb from the socket. Insert the new Auxbeam LED bulb, ensuring it is seated correctly. If the light does not illuminate, try reversing the bulb's polarity.
Test and Check for Errors — Turn on your vehicle's hazard lights or turn signals to test the new bulbs. If you experience hyper-flashing or dashboard error messages, you may need to install additional resistors (sold separately).
