406 Custom dial using Plasma back lighting
Why do we use plasma glow sheets ?
- So the rev counter can glow yellow or red
- We can get bighter colours on the dial
Plasma glow sheets enables us to distribute even light behind the dial and also allows
our needle to glow white whilst the dial glows blue. The housing of the speedo casing
has been designed to display the automatic gear selectors which stops the rev counter
dial from lighting up evenly.
Hence we place a plasma disc over this to allow the rev counter to light up.
It also means that you do not need to desolder and change any of the LEDs on the cluster
from orange to white.
The OEM LEDS for backlighting is usually orange as standard and the needles are usually
white as standard. This means that the numbers will glow orange if you leave the standard
LEDS in place and you do not fit plasma backlighting discs.
Some speedo casing modifications is needed to allow the power cables to run thro to the
outside of the speedo.Some basic soldering skills are also needed to connect to an internal
12v power source within the speedo - when connecting plasma power kit.
