Replacing indicator bulbs might seem like a small job, but it’s pretty important. Indicator bulbs are the lights that let everyone know you’re turning or changing lanes. If they stop working, it’s not just annoying, it can be unsafe and even get you a fine.
If you’re thinking, “how do I replace indicator bulbs myself?”, here’s a simple guide you can follow. And if it gets tricky, don’t worry, the team at Coastwide Service Centre is always ready to help.
What are indicator bulbs?
Indicator bulbs are the small lights that flash when you use your blinker. You’ll find blinker bulbs at the front, back, and sometimes even on the sides of your car. Some cars use the old-school filament type blinker bulbs, and newer models might have LED indicator bulbs instead.
When an indicator bulb blows, your blinker might start flashing faster or just stop working altogether. If you notice anything strange, it’s time to check your blinker bulbs.
How to replace indicator bulbs yourself
Step 1: figure out which indicator bulb is blown
First, turn on your indicators and walk around your car. See which blinker bulbs are working and which one isn’t. Sometimes they flicker weirdly when they’re about to blow too.
Step 2: get the right replacement
Not all indicator bulbs are the same. Some are small, some are bigger, and some are specific to your car model. Check your car manual or pull the old blinker bulb out and match it. If you’re unsure, just come and visit us. We can change that for you quickly.
Step 3: find your way in
On some cars, replacing indicator bulbs is easy. You just open the bonnet, reach behind the headlight, and pop the old bulb out. On others, it’s a bit of a pain. You might need to remove part of the headlight, a cover, or even the bumper just to get to the blinker bulbs.
Tip:
-
In small cars like a Toyota Corolla or Mazda 2, it’s usually straightforward.
-
In bigger cars like 4WDs or utes, the blinker bulbs might be deeper inside.
-
In European cars like BMWs and Audis, it can get tricky real quick — they love hiding the blinker bulbs!
Step 4: swap the bulb
Once you reach the blinker bulb, twist it or pull it out (depending on the fitting), and pop the new one in. Make sure it clicks in properly.
Step 5: test it
Before putting covers or lights back on, test your indicators. If the new blinker bulbs work properly, you’re good to go!
When replacing indicator bulbs gets tricky
Some indicator bulbs are easy, and you’ll be done in 10 minutes. Others are hidden behind weird panels, deep inside the engine bay, or jammed in tight spots.
If you run into problems like:
-
Can’t reach the indicator bulbs properly
-
Don’t know which type of blinker bulbs to use
-
Indicator bulbs still not working after changing them
It’s usually quicker (and less stressful) to bring it to Coastwide Service Centre. Our mechanics have all the right tools and can replace any blinker bulbs without issues. We also offer mobile mechanic services, so we can come to you and change the indicator bulb on the spot.
How often should you check your blinker bulbs?
It’s a good idea to check your indicator bulbs every few months. They can last for years, but sometimes they fail early, especially if you drive a lot at night or over bumpy roads.
Don’t wait until someone honks at you for not indicating, a quick walk-around check can save you hassle. It should be part of your car maintenance routine.
Can you upgrade your indicator bulbs?
Yes! If you’re replacing indicator bulbs anyway, you can swap out old filament bulbs for longer-lasting LED blinker bulbs (if your car allows it). LED indicator bulbs are brighter, quicker, and usually last way longer.
If you’re not sure if your car can use LED indicator bulbs, just ask us at Coastwide Service Centre. We’ll let you know what fits and install them if you like.
Replacing indicator bulbs isn’t always hard, but it’s not always easy either. Some cars are simple and friendly for DIY. Others are a real mission.
If you’re confident, give it a go using this guide. But if you get stuck, break something (it happens), or just can’t be bothered crawling under your car, our mechanics at Coastwide Service Centre are ready to help. We’ll swap your blinker bulbs quickly and make sure everything works perfectly, so you’re safe on the road again.
