THE NITTY GRITTY.

*Please note H7-1, H7-3, H7-5, and H7 all have different mounting brackets and are NOT cross-compatible*

Our all-new H7-3 Copper-Head™ LED Headlight Kit is designed for vehicles that have 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 compatibilities.

KEY LIGHTING BENEFITS

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

TECHNOLOGY 

  • CANBUS Friendly - resistive Canbus cancellation built-in
  • Unlike other platforms on the market, our Copper Heads LED Kit will not discolour or tarnish your vehicle's headlamp reflector or lenses. 
  • Electrically Protected again RFI and EM Interference 
  • Over and Under Voltage Protection 
  • Waterproof connectors
  • Plug and Play H7-3 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

Too small for the shown size.
Size: XX-Large, Color: Black, Size: XX-Large, Color: Black
I usually would buy XL size but in this case I bought XXL thinking since it's cotton it might shrink. But when I tried the T-shirt it was too small. My older XL sized T-shirt has 2 1/2" larger total shoulder width and 3" wider body width. See attached pictures. Length was also a bit shorter by about 1/2". I will to return it.

Super soft, runs small, long tail
High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.
