Parts for your 2013 Toyota Bb-Headlights

2013 Toyota bB headlights — what they do and how to look after them

Headlights are absolutely relevant and standard on the 2013 Toyota bB. That’s consistent with Toyota’s own vehicle documentation and with lighting requirements in Australia and New Zealand, including ADR 13/00 (lighting) and the NZ Land Transport Rule: Vehicle Lighting 2004, which mandate functioning headlamps on road-going vehicles.

On a 2013 Toyota bB, the headlights do two key jobs: they light the road ahead after dark and in foul weather, and they make the car more visible to others. Low beam is for everyday night driving and built-up areas, high beam throws light further down country roads when there’s no oncoming traffic. Many bB models of this era run halogen bulbs, some trims may have projector lenses or HID/LED options. The exact bulb spec can vary by market and trim, so it’s smart to confirm the type and wattage in the owner’s manual or the label on the back of the headlamp housing.

As part of regular servicing, it pays to give the bB’s headlights a quick once-over. Look for cloudy lenses, moisture inside the housing, cracked tabs, or discoloured reflectors. If light output is down, replace bulbs in pairs to keep brightness and colour even. Always match the correct base and wattage, and avoid touching the glass with bare fingers—use gloves or a clean tissue.

Electrical checks matter too. If a new bulb doesn’t fire, check the relevant fuse and relay, and inspect connectors for corrosion. A dab of dielectric grease on clean terminals helps keep moisture at bay. For yellowed lenses, a quality restoration kit can bring clarity back and restore beam performance, which helps with WoF/rego checks and night-time safety.

Aim is often overlooked. If the beam sits too low, night driving feels dim, too high and it dazzles others. Park on level ground facing a wall about 7.5 metres away, measure the cut-off against the vehicle’s headlamp centre height, and use the adjusters for small, even tweaks. If unsure, a workshop can set the aim to spec in minutes.

• Replace bulbs in pairs, keep a spare in the boot for road trips.
• Clean lenses and check aim at each service or every 10,000 km.
• Seal minor cap gaskets if condensation appears, persistent fogging may need a new seal or housing.

Popular questions about 2013 Toyota bB headlights

What bulb type does a 2013 Toyota bB use for headlights?
It varies by trim and market. Many JDM bB examples run a dual‑filament halogen (commonly H4) in a reflector housing, while some variants use separate low/high bulbs (such as H11/HB3) or projector setups. The definitive answer is on the headlamp’s rear label or in the owner’s manual.

If the car has aftermarket housings or LEDs, match replacements to the current housing spec and stay within legal output limits for Australia and New Zealand.

How often should headlight bulbs be replaced?
Halogen bulbs typically last 400–1,000 hours but can dim before failing. Many owners replace them in pairs every couple of years or when light output drops. HID/LED systems generally last longer but should be checked during routine services for colour shift, flicker, or aim issues.

Any sign of intermittent lighting, blown fuses, or moisture in the housing is a cue to inspect sooner rather than later.

How can the headlight aim be adjusted on a bB?
There are vertical (and often horizontal) adjusters on the back of each headlamp. Park on level ground about 7.5 m from a wall, measure from the ground to the lamp centres, and set the cut-off slightly below that line. Make small, equal adjustments side to side.

If the beam pattern looks odd or the adjusters are stiff, a workshop alignment is quick and ensures it passes WoF/rego checks without dazzling oncoming traffic.
