When one of your motorcycle or car headlight bulbs just stopped working, so you need to get a replacement. Instead of just getting the first headlight bulb off the shelf at your local garage or part shop, it's an opportunity to consider the car bulbs Australia that are now available to you.
Standard or OEM Headlight Bulbs 
Usually the cheapest option, these basic bulbs are direct replacement for the ones originally fitted by the manufacturer. While brand name bulbs are usually of good quality, avoid the very cheapest ones, as the lower price may affect both brightness and life.
Long Life Headlight Bulbs 
These are designed for vehicles that tend to leave their headlights on all the time, and are especially useful for car tail lights which use the headlights for daytime running lights, or that do very high mileages. Heavier filaments increase the lifespan of the bulb, and increase resistance to vibration. However, these bulbs to not provide any additional light, and can be a bit yellow, especially as they age. Long life bulbs cost a little more than the standard equivalent, but generally are cheaper in the long run due to their lifespan.
Upgraded Headlight Bulbs 
Boasting increased light output of up to 100% than standard halogen car headlight globes, these are a direct replacement that are fully road legal in the UK. Careful adjusting of the filament metals, gas and pressure allow these bulbs to produce more light for the same power requirements. The light is often a little whiter, and helps to highlight roadside objects such as signs and cats eyes. The only disadvantage to these bulbs is the cost: they can be significantly more expensive, but only have a similar life. There are some LED bulbs in headlight bulb sizes, but these are intended for show use only - the actual light output is quite low.
