Frequently Asked Questions

Will H4 / 9003 / HB2 LED bulbs fit my car?

H4 / 9003 / HB2 is one of the most common bulb sizes on the road. It fits any vehicle that uses the H4 / 9003 / HB2 socket for low beam, high beam, high beam / fog light or daytime running light. Check your owner’s manual, or pull out your current bulb and compare the base - if it matches H4 / 9003 / HB2, these bulbs are a direct fit. (99%+ vehicle compatibility.)

Do I need any adapter, decoder or modification?

No - these bulbs are CANBUS-ready with a built-in decoder, and the 1:1 mini housing fits the factory socket and cap exactly. Most vehicles will show no error code and no flicker. A small number of sensitive European cars may still need an external resistor (not included), which we can advise on. Plug in, twist-lock and you are done.

How bright are they compared to my stock halogen bulbs?

They produce roughly 58,000 lumens per pair - about 1200% more light output than a standard halogen bulb, with a clean 6500K white beam that makes road signs and hazards pop. You will notice the difference immediately on dark country roads and highways.

Is the 6500K white light legal and safe for daily driving?

6500K cool white is a standard aftermarket upgrade color and gives excellent contrast. The beam is engineered with a sharp cut-off line and focused pattern (1:1 filament position) to avoid blinding oncoming drivers. We recommend proper headlight alignment after install. Some regions have specific color/beam regulations - check local rules if your vehicle is used for inspection.

Will the bulbs cause error messages, flicker or radio interference?

No - the CANBUS-ready decoder prevents dashboard error lights (e.g. "bulb out" warnings) and anti-flicker circuitry keeps the beam steady. It also filters radio-frequency noise, so no static on AM/FM while driving.

Do these bulbs overheat or melt my headlight housing?

No - LED bulbs run far cooler at the lens than halogens. The built-in high-speed cooling fan plus aluminum heatsink actively pulls heat away from the chips, keeping operating temperature safe even in summer traffic. The 1:1 mini housing also leaves more clearance inside the dust cap.

Are they waterproof and durable in bad weather?

Yes - rated IP68, with fully sealed internals. They handle rain, snow, fog, mud and automatic car washes. The aluminum body is vibration-resistant, so they hold up on rough roads, washboard trails and off-road use.

How long do they last?

Rated up to 50000 hours of operation - roughly 10x the life of a halogen bulb. At average nightly driving that is many years of service. Backed by our warranty - if a bulb fails prematurely, contact us for a replacement.

How long does installation take?

Typically 10-20 minutes per pair for most vehicles. Remove the old bulb, plug in the new one, twist to lock, and re-fit the dust cap. No special tools required. We recommend checking bulb access in your engine bay first (some vehicles need the washer fluid tank or battery moved slightly).

Will they work in projector (not reflector) headlights?

Yes - the 1:1 mini size and precise chip placement work in both reflector and projector housings. The light source sits in the same position as the halogen filament, so the projector lens focuses the beam correctly with a defined cut-off. If your car has a very tight projector shroud, the mini body gives you the best chance of fitting without modifications.

What is in the box and what if something goes wrong?

You receive 2 H4 / 9003 / HB2 LED bulbs (matched pair, CANBUS ready) with installation guide. Every RENO order includes responsive support - if a bulb arrives damaged, does not fit, or fails within the warranty period, contact us and we will make it right.
