The Teralume Industries H4 LED conversion is designed to replace your factory H4 halogen globes, bringing your headlights into the modern world. You can expect much longer life and greater performance over halogen with far less current draw.

Fitment is easy! Our headlights are all plug and play which means no need for cutting, soldering or hacking of your wiring or headlights.

Halogen Vs. LED
A Clear Difference

A picture tells a thousand words! Our H4 conversion offers a substantial output increase from halogen while maintaining hyper-accurate beam characteristics.

State of the art sealed dual bearing cooling technology and top binned LED’s offers 4,441 lumens of brilliant white output per bulb. Choosing the right bulbs can be challenging as most other sellers gloat unrealistic performance figures. 

Every LED globe conversion has been designed and tested with proper photometric equipment to ensure light output and beam accuracy are perfect.

30,000 hours
Huge Life Span

There are many different types of LED bulbs on the market, mainly distinguished by their cooling methods – passive or active.

Active: Cooling fan
Passive: Copper belts or heatsink

There is no right and wrong, just what works best. Teralume’s headlight conversions feature a fully waterproof double ball-bearing fan. This offers the very best in cooling capacity while maintaining a compact housing and hyper-efficient cooling coefficient.
