NIGHTEYE New-Gen H4 LED headlight bulbs are a two-bulb conversion kit listed for 12V vehicles, with cool-white 6500K light and a cooling fan. The page claims 20,000 lumens per pair, but its detailed description gives that figure as a pair total, so treat the output claim as unresolved.

What to know before buying

Listing details to confirm

The listing is inconsistent about output and power: the title and details state 20,000 Lumens and 70 watts, while the product description states 20,000LM per pair and 70W/Pair (35W/Bulb). It also cites 32 chips in one claim and 12 CSP chips elsewhere, and lists temperatures of 40 Degrees Celsius and 80 Degrees Celsius while another section gives -40°C - +85°C. Confirm the exact bulb-level ratings and temperature range before purchase. Vehicle fitment is not guaranteed by the universal-fit label. The listing says a decoder may be needed for sensitive models.

Frequently asked questions

How many bulbs are listed in the kit?

The listing states 2 pieces and names LED headlight bulbs and a user manual in the contents list.

What is the claimed light output?

The title and specifications state 20,000 Lumens. The detailed description labels 20,000LM as the pair total, so the per-bulb output is not clear.

Will these bulbs fit every vehicle with H4 headlights?

The listing says universal fit but also recommends checking vehicle fitment and warns that sensitive models may need a decoder. Confirm compatibility for your vehicle.

Are these suitable for a 12V system?

The listing specifies 12 Volts. Confirm your vehicle's bulb type and electrical requirements before ordering.
