The PIAA LEH170E is a set of H4 LED bulbs designed for headlight and fog light applications. Utilizing ultra-thin, double-sided circuit board technology, these bulbs feature a controller-less design that enables a compact profile while maintaining accurate light distribution. Equipped with PIAA proprietary dual high beam technology, these bulbs brighten the entire area in front of the vehicle by simultaneously illuminating the low beams when the high beams are activated. They operate at 12V and 18W per bulb, delivering a color temperature of 6,600K for a clean, white light output. The total brightness for the two-bulb kit is rated at 3,800 lumens for the high beam and 3,000 lumens for the low beam. The bulbs are designed to be a direct replacement for standard H4 halogen bulbs, offering a compact body intended to mimic factory sizing for simplified installation. These components are Road Transport Vehicle Act compliant, though users should verify compliance with local legislation before installation.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
