Fascinating stuff....as my eyesight is getting worse at night a review of bulb brightness seems a good idea.....

The older we get our eyes get less sensitive to light. Natural deterioration of the retina. Eventually we will get to a point when we will have to stop driving at night. Even now I prefer to avoid doing it. I’m nearly 64 now.

Certainly illuminating, jumping from the standard 40/45w up to the 55w is a bright idea & will probably make a difference in itself but having the sparks at Guzzirider test lab makes it a dam lot easier choosing which bulb to jump too...Night breaker (rubbish name) are in the post so I look forward to carrying the torch of your advice & being a beacon of light next full moon....

How much life do you expect ? I ride with my lights on and at a guess I may replace a bulb every 50,000 miles.

Some good comparison brightness tests out there on the car reviews. Think I run an Ultraining at the moment.

Tailight bulbs last from 1 day upwards.

The one thing which will reduce light output is an connection between the battery and light bulb.
Automotive bulbs, though rated at 12v are designed to work at 14v. Drop that to 12, or 11 volts and you get at least 30% reduction in light output.
 
So before changing anything, with the engine running, check the voltage at the battery, then check again on the back of the bulb or as close to it as you can possibly get.
 
If there is a marked drop, think about fitting a couple of relays for main and dip beams.
 
If the battery volts are low as in under 13v, then the charging circuit needs attention.
 
The best bulb in the world won't help if you don't have enough volts there.

The only down side I have found with high output lamps is that they fail sooner than "std" lamps. My guess is that as they are under more stress they are super sensitive to higher voltages. One of my cars has an early implementation of a "smart charging" system which peaks about 0.3V higher than most (~14.7V depending on battery state of charge) and high output lamps only last around 12months. In the end I got fed up with replacing them and fitted long life bulbs which have been going for a few years now. The only down side of those is, you guessed it, lower light output. I considered LEDs but having experienced them in a friend's car (reflector type) the beam pattern makes them unusable as Brian said. In older vehicles with charging systems operating at ~14.0V the service life penalty of the high output bulbs may well be considerably less significant but I don't have any experience of them in that application.

High output bulbs run at higher temperatures, so the filament is stressed more. They should b designed to run at 14v though, but not much higher. They would definitely suffer at 14.7v, didn't realise some cars charged that high.
Certainly I used the nightbreaker bulbs without suffering too much from short life, but the charging wasn't up as high as 14.7v.

Systems with AGM type batteries charge higher .... but on a Guzzi the vibes wipe out cheap bulbs ....the works Sprinters get "ring" bulbs they fail regularly in fact the rate they go thro head and tail bulbs is in believable

Ring bulbs are not known for reliability.

Think it's a Sprinter thing, we have them at work too and they go through tail bulbs fast! I "borrow" the odd one from work for my little Honda, and they last for ages in that, despite the buzzy 1cyl vibes.

My experience with LED headlight bulbs is that they don't tend to last as long as you expect. There's not much heat sink on most of them, and the enclosure isn't well ventilated so they cook themselves to death. Power on vehicles is notoriously "dirty", which probably doesn't do the cheaper bulbs much good...
