Internal lighting is available as an option on all of the 2-1/4", 3-1/8" instruments (except for altimeter) and on the electronic engine gauges. The internal lighting uses the same EL light that is used in the bezel. This light strip is mounted around existing dial of the instrument., which allows for the instruments to be closer to the instrument panel and easier to read. Available only for UMA manufactured products.
This is just a lighted option. Order the instrument in addition to the internal lighting.
