Turn Signals: Car Blinkers, Indicator Lights and Side Signal Assemblies
A turn signal that flashes too fast, stays silent, or has stopped working altogether is not a small fault; it is the one signal every driver around you relies on to predict your next move. CBT Auto Parts stocks turn signal housings, indicator light bulbs, and side indicator assemblies for cars, utes, and trucks, each checked against genuine fitment data before it is listed.
Aftermarket blinkers and indicator lights are accepted practice once wiring and output match factory spec, and every part here does. This range works closely with Brake Lights, since the two functions often share a housing, and Marker Lights for side-mounted units. All three sit inside our wider Lighting & Signaling Parts family. Most orders ship within twenty-four hours.

Why a Fast Flashing Blinker Usually Means a Bulb, Not a Fault
Most drivers notice a turn signal problem the same way: a blinker on the dash suddenly flashing twice as fast as normal. That rapid flash is not a fault code or a wiring fault in most cases; it is the vehicle's hyperflash warning, triggered whenever a globe blows and the circuit senses reduced load. It is one of the simplest diagnostics in the entire vehicle, since a fast-flashing indicator light almost always points straight to a bulb replacement rather than anything deeper in the wiring. A double blinker, where both sides flash together instead of one, usually points to a blown fuse or a hazard switch fault rather than the turn signal bulb itself.
Turn Signal, Side Indicator, or Marker Light: Knowing the Difference
These three get confused constantly, and ordering the wrong one is the most common mistake in this category.
- Turn signals mount at the front and rear of the vehicle and flash to indicate a turn or lane change, either as a standalone lens or combined into the headlight or taillight housing.
- Side indicator lights sit on the front guard or wing mirror and repeat the same flash pattern, giving drivers beside you an earlier signal than the front or rear units alone.
- Side marker lights do not flash at all; they stay illuminated to outline the vehicle's width and length and belong to a separate category entirely.
If the part you are chasing does not flash, it likely belongs in Marker Lights rather than here.
Fitment Checks for Turn Signal Housings and Bulbs
Indicator housings vary more than most drivers expect across trim levels and model years within the same range.
- Confirm your make, model, and build year, since a mid-cycle update can shift the indicator lens shape without changing anything else externally.
- Check whether your turn signal is a standalone housing or built into the headlight or tail light assembly, since replacing the wrong one wastes money.
- For commercial vehicles, including popular Hino truck models, indicator light wiring configurations can differ significantly from passenger vehicles, so confirm the exact part number where possible.
- Note the globe base size fitted if you are only replacing the bulb rather than the full housing.
Our fitment team can confirm compatibility against your rego before you order if any detail is unclear.
Left, Right, or Full Kit: Ordering the Correct Side
Turn signal housings are side-specific, and left and right units are rarely interchangeable due to mounting bracket orientation. Before ordering, confirm which side has actually failed rather than assuming both need replacement, since a double blinker fault is often unrelated to the housing itself. Vehicles with left and right indicators sold only as a matched pair will have that noted on the product listing, while others sell individually. Checking this detail before checkout avoids receiving one housing when a pair was required, or paying for a pair when a single side would have solved the problem.
How Turn Signals Connect to the Rest of Your Lighting Setup
Indicator circuits rarely operate in isolation from the rest of the vehicle's lighting. A blown turn signal bulb pulls its replacement from the same range as a brake light globe or tail light bulb, and many housings combine flash, brake, and running functions into a single unit covered on our Brake Lights and Tail Lights pages. If your concern is a light that stays on rather than flashes, that almost always belongs to Marker Lights instead. And if the fix you need is a specific globe rather than a full housing, our Relay & Bulb Assemblies range stocks the individual bulb standards fitted across most turn signal setups.
Shipping and Support
Most turn signal orders dispatch within twenty-four hours, with metro delivery typically arriving in two to four business days and regional addresses taking slightly longer. Tracking is emailed the moment your order leaves the warehouse. If a housing arrives and does not match your mounting bracket, our lighting and electrical returns team manages the exchange directly.
