Keeping every bulb on your car working correctly isn't just good practice – a faulty indicator bulb or side light is a straightforward MOT failure, and driving with one out can catch the attention of the police as well as leave you less visible to other road users.
This range covers everything you need to put it right. Indicator bulbs are almost always orange or amber, helping other drivers clearly identify when you're signalling a turn or lane change, and we stock both traditional halogen orange indicator bulbs and modern LED indicator bulbs for a brighter, faster-reacting signal.
Alongside these, our side light bulbs illuminate your number plate and outline your car's width after dark, and are available as standard halogen or upgraded LED side light bulbs for a crisper, whiter light that better matches modern LED headlights and daytime running lights.
Whether you need a single side light bulb, a pair of car indicator bulbs, or a full set to keep as spares in the boot, this collection has you covered. If you're not sure which bulb fitting your car takes, our team of friendly experts are always here to help – get in touch for recommendations and advice, or use our parts finder to check compatibility against your registration. While you're topping up your bulb box, take a look at our headlight bulbs, rear light and brake light bulbs, and bulb sets and kits for a complete refresh in one go.
