# NIGHTEYE New-Gen H4 LED Headlight Bulbs, 6500K

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.

## At a glance

- The H4 bulb format is described as a compact, 1:1 mini size.
- A cooling fan and copper heat-transfer components are described in the product material.
- The listing claims tool-free, plug-and-play installation, while noting some vehicle models may require a decoder.

## Pros

- Supplied as a pair, with an H4 fitment and 12V specification stated in the listing.
- 6500K cool-white light and active fan cooling are specified.
- The listing identifies possible decoder needs for sensitive vehicle models rather than promising universal error-free compatibility.

## Before you buy

- 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.

## In the box

- User manual (Included)
- LED headlight bulbs \(2\) (Included): The listing gives a two-piece count.

## A good fit for

- Drivers replacing H4 headlight bulbs in a compatible 12V vehicle who want a cool-white LED conversion.
- Buyers comfortable confirming fitment and possible decoder requirements before installing LED bulbs.

## Less suited to

- Buyers needing confirmed error-free compatibility or verified beam performance for a specific vehicle.
- Buyers who need an undisputed per-bulb output, wattage or operating-temperature range before ordering.

## Customer feedback

Only aggregate rating information is supplied, with a mix of five-, four- and two-star ratings. This small sample indicates varied impressions but does not show what buyers liked or disliked, or establish fitment, beam quality or longevity.

## 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.
