How to Order a Lightning Overlay

The Lightning overlay presented some unique challenges. The capacity for being able to display added boost had to be handled very differently than the Cobra overlay. When the Lightning overlay is installed and the gauge recalibrated the position of the needle must be removed and “re-clocked” or rotated clockwise to a new zero reading.  This is necessary because there is only so much room on the stock gauge. Detailed, pictured instructions for installation and calibration are included with the overlay when purchased. As you can see from the photos of the installed Lightning overlay the stock numbers have been changed. The 0 and 10 have become 5 and 16. To accomplish this small squares have been printed on the overlay that closely match the color of the gauge face background. There is a slight difference in the color of the small squares and the stock gauge face. This slight difference is made less noticeable when the cluster is installed and viewed at the normal distance from the driver’s position. Then the new numbers 5 and 16 have been printed on top of the squares (see the photo). A new number 10 has also been added and printed in the new location on the clear part of the overlay. Because the 5 and 16 had to be printed in this manner the squares they are printed on become black during night time operation when the dash lights are turned on. I have included a night time shot to show this. I wanted to point this out to potential purchasers of the Lightning overlay in case this was a concern. I don’t want anyone to purchase one and have this be a disappointment after installation.
