Headlight bulbs used for motorcycles

"ISD" Modulation"© (Here's something you should read)
There's an important design feature that separates a Kriss modulator from others on the market. The program code for our microprocessor sets an "Instant Step Down" (ISD) method of controlling the current flow to the bulb. Our circuit design creates a more crisp and brighter modulation because it doesn't waste current with a heat generating delay like those that slowly throttle down the current flow. It's a characteristic of a mosfet (the switching transistor) to get hot when changing state slowly so we put in the additional engineering to make it work fast. When the filament is at peak temperature our "ISD" sets the bottom level with lighting speed allowing the filament to cool naturally according to the design and material of the filament used in the bulb. An obvious benefit is that the filament is not going to be stressed by operating outside it's metallurgical limits. Our modulators last longer because they run cold and don't create life shortening heat like the others you'll find on the market.

Headlight Bulb Identification for Motorcycles
Consult your owners manual or your local motorcycle dealer for the bulb type in your motorcycle.

Please note: A single headlight may have more than one bulb. The information below is based on the bulb type.

H4 type High/Low beam bulb.
- identified by 3 spades
(has two filaments - high & low) - use the Kriss Classic Single H4 (#H44001)
--------------------------------------------------------------------------------
Some motorcycles have a dual installation (two headlights) using two of these bulbs. - use the Kriss Dual H4 (#H44002)

Sealed Beam (H4 type) - Identified by 3 spades
(has two filaments - high & low)
7 inch headlights- use the Kriss Classic Single H4 (#H44001)
6 inch headlights - use the Kriss Single H4 Custom (#H44001S)
Harley-Davidson - use the Kriss Harley Single H4 (#H45003)

H(x) type bulb ( H7, etc.).
- Identified by 2 spades
(has a single filament)
These bulbs are used separately for high beam or low beam.

Two bulb installations use one bulb for low and one for high. - use the Kriss Single H7 (#H75001)
Four bulb installations use two bulbs for low and two for high). - use the Kriss Dual H7 (#H75002)

H(x) type bulb ( HB3, 9005, etc.).
- Identified by special 2 spade socket
(has a single filament)
These bulbs are used separately for high beam or low beam.

H(x type bulb ( H1, etc.).
- Identified by single spade, grounded by case or ground wire.
(has a single filament)
These bulbs are used separately for high beam or low beam.

Two bulb installations use one bulb for low and one for high. - use the Kriss Single H7 (#H75001)
