Technical Specifications

Why Choose This Product?

These Heise LED bulbs are designed for drivers upgrading aging HID systems in off-road applications. Their D2S and D2R fitment, adjustable collar, and built-in cooling system give you key details to consider when choosing a replacement bulb set.

The built-in EMI filter is intended to reduce interference with radio, GPS, and CB equipment. The listed startup is instantaneous full lumen, so the set reaches its stated output without a warm-up period.

Installation & Compatibility Notes

Confirm that your vehicle uses a D2S or D2R HID socket before ordering. Installation replaces the OEM HID bulb; in most applications, the factory ballast is bypassed or removed because these LED bulbs do not require one.

After installation, adjust the rotatable collar and check the beam cutoff against a wall. Vehicles with CANBUS monitoring may require a CANBUS decoder to prevent flickering or error codes. These bulbs are intended for off-road use only.
