H4 12V LED pirni komplekt - LG5017

LED Bulb Type H4 (Pair) – LG5017

High-output H4 LED headlight bulbs for drivers who want a clear, modern beam without rewiring the vehicle. The LG5017 pair delivers up to 380% more brightness than standard halogen, with a crisp 6000 K colour that cuts through dark, wet roads. Designed for straightforward plug-and-play replacement on 9–16 V systems.

These H4 LED bulbs are built for work vehicles that run at night and in all weathers. Instead of a vague yellow pool of light from old halogens, you get a sharp, consistent beam from 1800 lm (low beam) and 2500 lm (high beam) per bulb (±10%). That means better reaction time, less eye strain, and more confidence on unlit roads, rural routes, and construction sites.

The LG5017 is engineered around thermal control, because heat is what kills most cheap LED conversions. A pure copper plate with thermal conductivity around 60× higher than ordinary aluminium pulls heat away from the LED chips. That heat is then pushed out through an aluminium shell and a dual ball silent fan, so the bulbs hold their output instead of dimming as they warm up.

An intelligent temperature control IC constantly watches the working temperature and automatically adjusts power if needed. So the LED chips stay within a safe range, protecting light output and service life. Power draw is controlled and predictable: 22 W on low beam and 32 W on high beam, within a 9–16 V DC electrical system, ideal for modern 12 V passenger and light commercial vehicles.

Installation is straightforward. These are H4 plug-and-play bulbs, so no cutting, no extra relays, no resistors for basic operation in most vehicles. The compact cooler and integrated fan are designed to fit within typical headlamp housings, making them a practical upgrade for fleets or tradespeople who need fast changeovers in the workshop. As with any LED headlight retrofit, always check local road regulations and vehicle approvals.

Key Features

• H4 LED headlight bulbs – sold as a pair
  Direct replacement for standard H4 halogen bulbs, ideal for headlamps with combined low and high beam.

• Up to 380% increased brightness
  Strong upgrade over stock halogen, improving visibility on unlit and rural roads without rewiring the vehicle.

• High light output – 1800 lm low / 2500 lm high (±10%)
  Delivers consistent, focused illumination for both dipped and main beam, supporting safer night driving.

• 6000 K cool white colour temperature
  Produces a crisp, daylight-style beam that helps pick out road markings, signs, and hazards earlier.

• Optimised power draw – 22 W low / 32 W high
  Efficient LED design reduces load on the electrical system compared with many high-wattage halogens.

• 9–16 V DC operating range
  Suited to most 12 V passenger cars, vans, and light commercial vehicles with H4 headlamp fittings.

• Aluminium shell with efficient heat dissipation
  Metal housing acts as a heat sink, transferring heat away from the LED chips to extend service life.

• Pure copper thermal plate – 60× higher conductivity than standard aluminium
  Rapid heat transfer from the LED base into the cooling system, helping maintain stable brightness.

• Dual ball silent cooling fan
  High-speed, low-noise fan supports active cooling, keeping the LED package within its design temperature during extended night runs.

• Intelligent temperature control IC
  Electronic control monitors temperature and adjusts power when necessary, protecting the LEDs from thermal stress.

• Plug-and-play installation
  Uses the existing H4 connector, reducing downtime in busy workshops and fleet environments.

Ideal Applications

• Light commercial vans and service vehicles running early-morning or night routes.
• Fleet cars and pool vehicles that need safer night-time performance without complex electrical upgrades.
• Rural and agricultural vehicles using H4 headlamps on unlit back roads and farm tracks.
• Trades and construction vehicles frequently entering poorly lit sites or industrial yards.
• Private cars whose owners want a cleaner, whiter H4 beam with higher output than stock halogen.
