ACE-HID-D4R-4300K

This D4R HID xenon bulb produces a warm, bright white close to factory xenon output at a colour temperature of 4300K. It is designed as a direct replacement for factory D4R xenon bulbs used in reflector-style headlights with a built-in shield (R type).

HID bulbs create light with an electric arc rather than a filament, giving much stronger output and a longer service life than standard halogen globes. Replacing a dim, flickering or colour-shifted bulb restores the beam pattern and night-time visibility your headlights were designed to deliver.

Fitment and safety

Confirm that your vehicle uses a D4R bulb before ordering. Xenon systems operate at very high voltage during start-up, so always switch the lights off, disconnect the battery and allow the system to cool before working on it. Do not touch the glass with bare fingers. For even colour and brightness across both sides, replace bulbs in pairs, and check headlight aim after fitting.

Buying the correct part the first time saves on labour, avoids repeat jobs and gets the vehicle back to work sooner. Always follow the vehicle manufacturer's service schedule and fitting instructions, and have the work carried out by a qualified technician if you are not confident doing it yourself. Our team is happy to answer questions about specifications, compatibility or ordering in larger quantities for fleet and workshop use. If you are unsure about fitment, send us your vehicle registration, make, model and year before ordering and we will help you confirm the right part. Quality replacement parts like this help keep running costs predictable and reduce the chance of an unexpected roadside breakdown. Good headlight performance matters on unlit rural roads and in poor weather. Every part is checked against its part number before dispatch, so what arrives matches what you ordered. Store spare parts in a cool, dry place in their original packaging until they are needed. Keeping a spare on the shelf is a sensible move for workshops, fleet operators and home mechanics who would rather not wait on parts.
