2014 Toyota bB headlights: purpose, maintenance and replacement

Headlights are absolutely relevant and fitted to the 2014 Toyota bB. Toyota’s own service and owner literature for the QNC20/QNC21 series lists headlight controls, bulb specifications and replacement procedures, and the vehicle must comply with Australian Design Rules (ADR 13/00 and ADR 46/00) or the equivalent UNECE lighting regulations when on Aussie or Kiwi roads. Put simply, the 2014 bB is designed and certified to run low and high beam headlights, with halogen reflector units standard and some trims offering HID/Xenon options.

On this model, headlights do two key jobs: help the driver see down unlit roads and make the bB visible to everyone else. Low beam handles everyday night driving and wet-weather duties without dazzling oncoming traffic, while high beam throws a longer, brighter pattern for open-road visibility. Many bB imports into Australia and New Zealand are JDM spec, so daytime running lamps may vary by trim, but the core headlight setup remains essential for roadworthy compliance and safe night driving.

For servicing, it pays to treat headlights like any other wear item. Halogen bulbs slowly dim with age, so replacing them in pairs keeps the beam pattern even. Cloudy lenses can sap light output—polish and UV-seal them, or replace the housings if the plastic is crazed or yellowed deep into the material. Bulb type can differ by grade, many 2014 bB examples use an H4 dual‑filament bulb, while others split duties with H11 low beam and HB3/9005 high beam. Always confirm against the owner’s manual or the vehicle’s parts catalogue before buying. If equipped with HID/Xenon, the high-voltage system and ballast are best left to an auto sparky.

• Inspect headlight operation at every service or WOF/roadworthy check, look for flicker, uneven colour, or dim output.
• Keep the lenses clean and clear, wash off road grime and reapply UV protectant after restoration.
• Avoid touching new bulb glass, use gloves and check the connector for heat damage.
• Check fuses, relays and grounds if a light is dead, don’t overlook aiming after any front-end work.
• Adjust aim on level ground, correct alignment prevents glare and maximises reach.

Popular questions

What bulb type fits a 2014 Toyota bB?
Bulb type varies by trim and market. Many 2014 bB units use an H4 dual‑filament bulb, while others run separate H11 low beam and HB3/9005 high beam. Being a common JDM import, spec can differ, so it’s smart to confirm with the owner’s manual, the VIN/parts lookup or by checking the existing bulb markings before purchase.

How do you adjust the headlight aim on a 2014 bB?
Park on level ground about five metres from a wall, measure from the centre of each headlight to the ground, and set the cutoff just below that height on the wall. Use the adjustment screws on the headlight housing for vertical (and where fitted, horizontal) aim. For HID-equipped cars or if carrying loads often, a workshop can set aim to ADR/UNECE specs with a beamsetter.

Why are the headlights cloudy and can they be fixed?
That haze is UV damage to the polycarbonate lens. Light to moderate clouding can be restored with proper sanding, polishing and a UV sealant. If the lens is deeply crazed or the internal reflector is dull, replacing the headlight assembly is the better bet for safe output and a clean look.
