J.W. Speaker LED H4 Direct Fit Headlight Conversion Kit
Premium LED Technology with TST Cooling
Replace your tired halogen headlight globes with this modern, ultra-bright and long lasting LED solution. The Direct Fit LED headlight conversion kit features TST (Thermal Stabilization Technology) cooling - a new and important cooling technology that sees the LED chips attached directly to the alloy shaft of the bulb instead of using PCBs and thermal silicone like most LED bulbs. This process allows for more even heat distribution, reducing strain on the LED chips and leading to longer life and more stable beam performance.
Direct Fit Design
These bulbs share an identical connection system to the halogen bulbs they replace, meaning no extra wiring or modules need to be fitted into the headlight. The Direct Fit range is as simple as removing the old halogen bulb and replacing it with the new LED bulb - true plug-and-play installation.
