What is a NULITE?
Nulites are supplementary light wedges that fit between your instrument and panel. You can pick and choose which instrument that you want to light and then order ONLY the lights you need. There are no holes to drill and nothing else to mount. They tie into your existing lighting system.
What happens if a bulb burns out?
The bulbs come to us with a 16,000 hour life expectancy. If by some remote chance a bulb burns out then we will replace the unit. Just send it back to us and we will repair or replace the unit. The bulbs are replaceable by removing the P.C. board on the top of unit and replacing the bulbs.
have a D.G. with two cut outs. Which one do I use?
Actually, the shafts on D.G.’s go though the mounting holes located at the 5 and 7 o’clock positions. Just remove the knobs using a .050 Allen wrench and slide the NULITE over the shafts and then replace the knobs. Be sure that you set the knobs high enough on the shafts to guaranty proper operation. If you need to “open up” the mounting holes a little to insure smooth operation it is permissible.
What if I have to modify my lights?
NULITEs are built to within .005” tolerances but we have found not all aircraft or instrument panels are built to those same high standards. If modification is required use a high speed dremel and take your time. The only thing that will hurt a NULITE is the vibration you get from a heavy grinder. Cover the reshaped NULITE with some type of acrylic white paint. You will notice a slight difference in the reflectivity but it will not be so great as to make it unusable. Note however that any change to the NULITE voids the warranty.
How much current do they draw?
The average current draw is 80 ma per unit with a max. current of .125 ma. Ea
What size pot do I need to install?
If you are going to install a separate pot for your NULITEs you should consult with your local Mechanic or Avionics shop. To determine the size of pot you may need for your particular installation consult the potentiometer page.
