Frequently Asked Questions
Question: "Why do the blue LEDs cost more ?"
Answer: The material used to manufacturer the blue LEDs are more expensive (indium gallium nitride on a sapphire substrate). The manufacturing process is also more involved, hence the cost.
Question: What color leds are the brightest ?
Answer: The specifications on the LEDs are 2000 mcd (milli-candels) for the red, green and yellow LEDS ( per LED). The blue is 3500 mcd (per LED). To the human eye they seem to be equivalent in brightness.
We have recently changed LED specs and upgraded the green LEDs. The green is much brighter now. You will not miss ANY of these LEDs even in direct sunlight.. **NOTE**: It is recommended to use the colored cap for night driving to reduce the emitted intensity.
Red LEDs are the most popular.
Question: "Will the shift light work on my vehicle?"
Answer: If your vehicle has a "tach output" wire from the ECM/PCM or if it has a coil, coil-pack or distributor-less ignition with individual coils, it will work. In some cases you can connect to one of the fuel injectors and set the shift light to "1 cylinder" mode to get an accurate reading of RPM.
The shift light will not work on ignitions typical of ATV and off road bikes (CDI).
**Do not connect to high energy coils such as MSD coils. Rather, connect to the ignition box "tach out" lead.
Question: "Will the dual mode shift light work on my vehicle?"
Answer: The dual mode shift light taps into the same tach lead as the normal shift light (see question above). The dual mode shift light also uses the signal going to the speedometer to switch between launch and shift mode. You must have a speedo signal or a pulsed output when the vehicle is moving and no pulse when the vehicle is stopped.
Question: "Is the shift light waterproof ?"
Answer: The shift light was primarily designed for automobiles but we have had increasing interest in motorcycle applications. We are looking into a water resistant version for motorcycles.
Question: "Are the shift lights capable of monitoring RPM above 9900 RPM ?"
Answer: Yes! If you want to set a shift point at say, 12,000 RPM, double the cylinder selection (if it would normally be 2, then set it for 4) then set the shift light to 1/2 the desired shift point. In this example, it would be set to 6,000 RPM. The shift light would activate at 12,000 RPM.
Question: "Why won't my shift light come on at the desired shift point ?"
Answer1: First of all, make sure you have power. The LEDs should test after turning the key switch to "on".
Answer2: If you are using wire tap connectors (insulation displacement connectors) make sure you have the appropriate size. The wires in the shift light cable are 22 gauge in size. If the wrong connector (rated for larger wire) is used, it may not be making a good connection to the conductor.
Answer3: Also, make sure that the "cylinder selection" switches are set to the correct setting to match your vehicle.
