Copper Head LED Headlight Conversion Kit H4 Replacement for factory Halogen bulb. H4 Fan-less Globe




Our all-new H4 Copper-Head™ LED Headlight kit is designed for vehicles which have the enclosed headlight bulbs that prevent our fanned Night Pilot kit from being installed. We’ve tested a nauseating amount of different “no fan” LEDs, and ultimately rested on our Copper Heads™ for its excellent light distribution, brightness & durability.

MATERIAL & THERMAL MANAGEMENT - Staying cool is the end all and be all in the world of LED.  Well executed thermal management means higher drive current leading to higher light volume.

  • Six 100% Pure Copper(Cu) belts allow maximum thermal conductivity.  The thermoelectrically separated copper substrates allow heat to transfer to the substrate efficiently and quickly.
  • American made Down Corning® thermal paste to increase conductivity to 6063 aluminium tower.  
  • No fan means modern vehicles which have rigid dust-covers or fully enclosed headlights bulbs can upgrade to LED without modifying the dust cap or worse leaving them off altogether.
  • Smaller driver footprint for tight applications.
  • Near identical footprint to stand halogen bulb ensure 100 compatibility.


  • Top Bin Philips© Lumileds Luxeon ZES® LED | We’ve independently verified the authenticity of the Philips© Lumileds used.  The undomed nature of the ZES® provide better optical control with minimal scatter.
  • CCT 5700K means colours sync with our auxiliary LED driving lights.
  • OEM matching light distribution through exact positioning of the LED emitters to optimise the vehicles reflector design as the OEM intended.
  • Instant Full Beam without any warm up time.


  • CAN-Bus cancellation built in 
  • Unlike other platforms on the market, our Copper Heads LED Kit will not discolour or tarnish your vehicles headlamp reflector or lenses. 
  • Electrically Protected again RFI and EM Interference 
  • Over and Under Voltage Protection 
  • Waterproof connectors
  • Plug and Play H4 Connector | No cutting or professional installation required, as easy as changing OEM bulb
  • Ingress Protection IP65 | means our kits will not fail at the first sign of water.  
  • True White 5700Kelvin

Installed these into my 80 land cruiser as the light weren't. Great product and easy to install, could not believe the difference they made from the standard lights and as always the service from Stedi was excellent. Cant wait to get the Type x spot light to go with my 42" bar. (Posted on 1/02/2018)
px led headlight upgrade
Review by Brad
ordering was v easy, with the required h4 canbus units automatically included. delivery was less than a week and the install instructions were easy to follow. Quality of the items met my high expectations, based on a stedi lightbar that I'm very happy with, purchased about 2 years ago. good value for money. (Posted on 6/12/2017)
