ACE-HID-D5S-4300K

This D5S 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 D5S xenon bulbs used in projector-style headlights (S 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 D5S 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.

Workshops can order with confidence for customer vehicles, and private owners can tackle routine maintenance knowing the part is made to suit the job. Every part is checked against its part number before dispatch, so what arrives matches what you ordered. Pairing this part with a general inspection of the surrounding components is good practice, as related parts often wear at a similar rate. 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. Older xenon bulbs often drift towards a pink or purple tint and lose brightness well before they fail completely. Buying the correct part the first time saves on labour, avoids repeat jobs and gets the vehicle back to work sooner. Store spare parts in a cool, dry place in their original packaging until they are needed. Our team is happy to answer questions about specifications, compatibility or ordering in larger quantities for fleet and workshop use. Keeping a spare on the shelf is a sensible move for workshops, fleet operators and home mechanics who would rather not wait on parts.
