Nulite aircraft instrument lighting creates the appearance of an internal lighting kit with less install time and at a fraction of the cost. Light wedges are installed between the instrument and the panel, effectively reducing glare and hotspots by concentrating 60% of its light to the upper half of the instrument. Nulite light wedges come in different sizes and cutout arrangements to fit most instruments and will work with existing dimming systems. These lights can be installed in minutes and are PMA approved.This Nulite light wedge (EDMO# LW3014AB) fits over 3-1/8 inch standard instruments, left & right cutout, and 14-volt operation.
