More on LED's: LED's can be bright (see above), they take less power, produce almost no heat, and they are more resistant to vibration. wBW Visitor "S.A." confirms this: "Greetings from Japan! One thing that you have not mentioned is durability. In off-road or dual purpose bikes the incandescent bulbs can take a beating. I have a 95 RMX250R that is a re-import to Japan, this bike in a US model that was brought back to Japan and at that point it was registered for the road (only the "S" model is road legal in Japan). There is not much under-tail support on this bike, so the stock incandescent bulb in the tail of the RMX would last about a week. I've had an LED light in there for over 6 months now! The LED also draws less and is bright even when the bike is idling, the incandescent light is almost nonexistent when the bike is just idling. Just a couple of points I thought you might want to hear about." | Interesting article explaining the importance of LED viewing angles and brightness

Bulb Nomenclature: An H4 bulb is also referred to as a 9003 or an HB2; the 9005 bulb is also referred to as an HB3; a 9006 bulb is also referred to as an HB4. Many motorcycles take an H4 (9003) bulb - check your owner's manual. Be careful of how much juice your wiring and switches can take! You may need to rewire and/or go through a relay. Interesting light bulb FAQ on this page at Coolbulbs
Bulb Brightness - Color Temperature: Color temperature is measured in Kelvin units (K). Higher K values mean "whiter" light. For example, incandescent light bulbs are around 2800K; a stock halogen bulb has a color temperature of around 3200K; the so-called "performance" bulbs run about 3500K; Xenon bulbs run near 4000K; HID lighting systems run from 4000-5000K and daylight is 5400K . Note that there is a difference between output (lumens) and color, or "whiteness" (Kelvin units).
Turn Signal - Brake Light Bulbs: Check out this wBW article with conversion chart on substituting different types of incandescent brake light and tail light bulbs for your OEM bulbs - you can get more brightness with the correct replacement. Explains similarities and differences between 21/5W, 2057, 1034, 1157, 2397 and 2357 bulbs
Halogen vs. Xenon Bulbs: This is where it gets confusing. There are all sorts of unsubstantiated and marketing claims made for various types of lighting. Xenon gas is sometimes used under pressure to fill the bulb; it supposedly cools the filament, and the Halogen on the filament can create increased light output. Whether or not Brand "X" is manufactured correctly is anyone's guess! See below for online sources for light bulbs
HID Lighting: High Intensity Discharge (HID) is a type of lighting technology that replaces the filament of the light bulb with Xenon gas. An arc is produced when voltage is applied, which results in light. It is claimed that HID lights can produce as much as three times the output (lumens) of a standard halogen bulb. An HID light also has a higher Kelvin light temperature (almost near sunlight) that gives it a very "white" light. See the wBW article on installing an HID lighting system | Tips on installing an HID light on a motorcycle | HID systems for motorcycles; apparently HID systems with both low and high beam in the same unit are hard to find | Baja Designs H.I.D. lighting kit | HID lighting that supposedly plugs in to existing H4 receptacles | The Xenon Depot has a high/low beam HID replacement light for motorcycles | Various types of motorcycle Xenon headlight conversion kits at Sports Imports | J.W. Speaker HID drop-in HID headlight conversion for motorcycles, uses an HID low beam and Halogen high beam | Harley Davidson HID lights to fit stock or near-standard headlight shells | Nice HID information page on the J.W. Speaker lighting site
Can You Increase Your Light Output?: Opinions vary; it appears that a lot of it depends on the size, shape and quality of your motorcycle's headlight reflector and also the bike's wiring. Some tests on the "superwhite" type bulbs show that the bulbs actually decreased output! But many owners claim much better visibility; could it be the increased K values change the perceived brightness?
All LED's Are NOT Created Equal!: I'm a big fan of LED's for use on motorcycles (less heat, use less power, more resistant to vibration, etc.) but some LED's are much better than others. We occasionally will receive an email telling us that some company has an LED replacement for $5.95, and that we're crazy for spending more. Just for the record, there are cheap LED's and their are good LED's. The cheap ones can have as low as a 5 degree wide light spread plus they can be very dim. The really good LED's currently have a 120 degree light spread and put out 4,000 milli-candela per LED -- but you'll pay for them. It doesn't make any sense to try and improve your rear lighting but use cheap LED's that actually decrease visibility instead.
LED Turn Signal Flashing Problems? In very rare instances, an LED bulb used for a turn signal may cause the bike's electrical system to either indicate that a bulb is burned out. This may be manifested by an increased flashing rate. The reason for this may be that the bike's electrical system isn't picking up the fact that there's a bulb because of the very low power consumption of the LED. This problem can usually be solved by adding a load resistor wired across the turn signal bulb to simulate a filament bulb load. Load resistors are available at Super Bright LEDs
