Couple of things to be aware of when fitting higher wattage bulbs, Greater power requirement producing more heat.  😮 If you go to a to higher wattage you can actually cause what is sometimes called smoking, this is when the reflector gets burnt by the heat and therefore looses efficiency. Also the plug on the back of the bulb can become cooked and brittle.Thats not to say you shouldnt fit higher wattage, just dont go overboard with it!!  😀

Yep, Narva is the go. You should try the new bulb called Blue Power that they say delivers 80% more light than a standard headlight bulb and the beam is 20% whiter – which adds up to 100% more night-time vision.The enhanced halogen technology used in Blue Power was developed in Germany, where the new lights are also manufactured. It combines the performance of the Plus and Arctic Blue ranges, effectively providing two lights in one – it may seem strange, but blue headlights deliver a whiter beam.The brilliance of light is measured in Kelvins and Blue Power is rated at 3750 Kelvin, which almost doubles the measured luminance of standard headlight bulbs, i.e. more light on the road. They don’t give out any more heat or draw more power from the battery than a standard bulb, meaning they are suitable for use with polycarbonate lenses.NARVA is supplying Blue Power globes in H1, H3, H4 and H7 specifications, with full ECE and ADR approvals. $36 at your local automotive outlet.CheersGarry

Hi CavalierNZ,By the way I have ordered some LED running lights for my tail-light.  I will let you know how they are.Did you get the LED "running light" for your taillight and is it a light brake light? I see they sell them - a bayonet fit in Dick Smiths for about $12.00 but have not taken the lens off yet to see if they taillight is the same? Have you found them to be better or are you still waiting for delivery?There was an article in a recent two wheels magazine about LED taillights and they showed photographic evidence of how good the LED was over the standard bulb and I am keen to put one in if the result is keeping the goons behind me from getting so close!Cheers, 😉

Hi CavalierNZ,I wonder if the LED light from Repco is different from the one from Dick Smiths? I tried a 19 LED bulb and they are not very good at all  :x. They work alright but the LED's are very directional and because the rear light lens unit is designed for a conventional filament bulb and use the 360 degree reflection from the bulb, the directional LED bulb does not "fill" the lens with light. The LED does not also provide the rear number plate illumination through the clear plastic window in the lens.So what type is the Repco unit? a complete light unit (reflector, lens bulb etc) on its own? 😕Cheers,Mike
