This is without a doubt the very best shift light available today having a Super Tiny profile of 13mm X 61mm (.5in X 2.4in) and weighing a mere 49 grams (1.7oz) complete with loom.
Within the 100% Carbon Fiber case is  a full Microprocessor sampling your RPM signal in 16bit resolution at 0.0000045 of a second (222,222 times per second).

In addition to this there are 3 intensity settings so that you won't get blinded at night or not see it on a bright summers day. The DSII also is touch sensed so there are no switches or buttons, you simply touch it with your finger and it will react immediately.

The DSII-L is without a doubt one of the very best shift lights available today having a Super Tiny profile of 13mm X 61mm (.5in X 2.4in) and weighing a mere 55 grams (1.9oz) complete with loom. Within the 100% Carbon Fiber case is  a full Microprocessor sampling your RPM signal in 16bit resolution at 0.0000045 of a second (222,222 times per second).
The core difference between the DSII and the DSII-L is that the later has a Launch Control feature and as such can interface with the Gizzmo Launch Interface. The other main difference is that the DSII-L has a White LED outside ring and a Blue center pre-shift LED.
In addition to this there a 3 intensity settings so that you won't get blinded at night or not see it on a bright summers day. The DSII-L also is touch sensed so there are no switches or buttons, you simply touch it with your finger and it will react immediately.

Gizzmo's launch Interface integrates with the Gizzmo Tach Recall
Shiftlight to enable the fully adjustable launch control function. The launch control function induces sequential misfire events at the desired rpm set by the user.
In a turbo application, having the throttle open while inducing misfire
increase the velocity and density of exhaust gases, allowing the turbo to spool up and generate boost with load. This results in boost being
generated before launching and therefore allowing a vehicle to launch with considerably more power. The ignition cut is clutch activated
allowing flat changing (the ability to change gear without removing your foot from the throttle). With the clutch engaged the rpm will pull back to the launch rpm previously set by the user in order to avoid over reving, this results in the vehicle not coming off boost while moving through the gears.
Launch control can benefit natural aspirated cars by giving a consistent launch rpm for best results every time, and enable quicker gear changes through flat changing.
