Changing the brake light bulb on the Vauxhall Corsa D requires removing the tail light cluster from the inside of the boot — the lights don’t simply pop out from the outside. The driver’s side (shown here) is the trickiest because of the tyre inflator kit that takes up space in that corner, but once you know what needs to move it’s a simple job.
While the light is out it’s worth replacing any other bulbs that look tired — an indicator bulb was also replaced on this one. The bulb types are a 382 brake/tail bulb and a 581 indicator bulb.
Why a Working Brake Light Matters
Brake lights are a legal requirement under the Road Vehicles Lighting Regulations 1989. Driving with a failed brake light is a fixed-penalty offence — if stopped by police you can receive a £60 fine and three penalty points, and the vehicle may fail its next MOT if the fault is not corrected before the test. More importantly, a failed brake light is a genuine safety hazard: drivers behind you have no warning you are slowing down, significantly increasing the risk of a rear-end collision.
On the Vauxhall Corsa D, the brake light cluster contains multiple bulbs: the main brake/tail light (382) and the indicator (581). When one fails it is good practice to replace both the failed bulb and its opposite-side equivalent at the same time — bulbs of the same age and mileage tend to fail close together, and replacing them as a pair saves a second job in a few weeks. Bulbs are inexpensive enough that this makes sound economic sense.
Bulb Types and Specifications
The Corsa D uses standardised bayonet-fit bulbs that are widely available from motor factors, online retailers, and supermarkets. The main brake and tail light uses a 382 bulb (21W, single-filament) and the indicator uses a 581 bulb (21W). Both are standard push-and-twist bayonet fit bulbs — the same type used in a vast range of popular UK cars.
Standard halogen bulbs are the basic replacement and cost as little as £1–£2 each. Higher-performance halogen options (such as Osram Ultra Life or Philips Long Life) cost a little more but last significantly longer and produce a brighter output. LED brake light bulbs are also available as a direct 382 equivalent, offering longer life and a faster illumination response time. However, some LED bulbs can trigger an error on vehicles with bulb monitoring systems — if a dashboard warning light appears after fitting an LED, you may need a resistor adapter or to revert to a standard halogen bulb.

Open the Boot & Remove the Inner Panel
Open the boot. On the driver’s side you will see a plastic inner trim panel. Put your finger behind the top edge and pull sharply to pull the panel away from its clips — it will come out. Set it to one side.
Remove the Tyre Inflator Kit
On the driver’s side there is the tyre inflation kit and the filler bottle stored in this corner. Take these out first. This section of foam and storage can be lifted and removed from the boot — work it slowly to avoid cracking any clips, then set it all to one side. This reveals the back of the light cluster.
Undo the Two Light Fasteners
With the foam storage section out, you can see two plastic fasteners holding the tail light in from inside the boot. Unscrew both of them by hand (they just need a few turns). With both undone, the light unit is free from the inside.
Pop the Light Unit Out
Go around to the outside of the car. Put your fingers behind the top of the light cluster and pop it outward — it has a couple of clip holders on the side that release with gentle pressure. Disconnect the wiring connector by pinching and pulling it off. The light unit is now free.
Access & Replace the Bulbs
The bulb holder is secured by three tabs — pull each tab back and it will release. Once all three tabs are free the bulb holder comes away from the light lens. Push and twist each bulb anti-clockwise to remove. Fit the new 382 brake bulb and 581 indicator bulb by pushing and twisting clockwise. Reconnect the holder to the lens, ensuring all three tabs click back in.
Refit the Light & Trim
Reconnect the wiring connector to the back of the light. Line up the light cluster with its aperture in the body and tap it gently home so the clips engage. Refit and tighten the two plastic fasteners from inside the boot. Replace the tyre inflator kit and foam section, and refit the inner trim panel by pressing all clips home.

Frequently Asked Questions
How do I know if my brake light is out if I can't see it myself?
The simplest method is to ask another person to stand behind the car and confirm both brake lights illuminate when you press the pedal. Alternatively, park close to a wall or another vehicle and watch for the reflected glow from behind the car when you press the brake. Some modern vehicles have a bulb failure warning in the instrument cluster, but this is not universal — older Corsa D models may not display a warning for a failed brake light.
Do I need to replace both brake lights at the same time?
It is not strictly required, but it is strongly recommended. Both bulbs were fitted at the same time and experience the same number of heat/cool cycles. When one fails, the other is typically close to the end of its life too. Replacing them in pairs is inexpensive insurance against needing to repeat the job very shortly afterwards. The same logic applies to headlight bulbs and indicators.
Will an LED brake bulb work on my Corsa D?
LED 382-equivalent bulbs are available and will physically fit the Corsa D bulb holder. However, the Corsa D's electrical system may interpret the lower current draw of an LED as a bulb failure and trigger a dashboard warning or cause hyperflashing on indicator circuits. If you wish to use LEDs, check that the product specifically states it is compatible with vehicles that have bulb monitoring systems, or be prepared to fit load resistors. Standard halogen bulbs remain the simplest, most reliable choice.
My brake light works but the tail light doesn't — is that a different bulb?
On the Corsa D the tail/brake function uses a dual-filament 380 bulb on some clusters, or separate single-filament bulbs depending on the exact trim level and year. If your brake light (bright flash when pedal pressed) works but the tail light (lower-intensity running light) does not, the tail light filament or bulb has failed. In this case, replace the tail light bulb. The 382 reference covers single-filament brake bulbs — check your specific cluster for the exact bulb type needed for the tail function.
