HLA, HLB, HLC & HLD Indicator Lights

The H-Lite  series provides a highly reliable indicator light assembly that requires a minimum of panel space. These units use the T-1 flange- based lamps- and both lamps and lens caps are replaceable from  the front of the panel without any special tools.

H-LITES allow the designer a number of mounting configurations and a choice of lens styles, colors and metal finishes. H-LITES are attractive, easy to install, and meet applicable military requirements of MIL-L3661

Other H-LITE series features are optional water tight and RFI shielded models.

HLD-Lampholder
---------------------------------------------------------------------------------------------
Two terminal front or rear mount Lampholder terminal isolated from case and panel Hex nut or knurled ring movable flange Bright or black nickel finish.
.312” mounting hole - .562” centers panel up to, 234” thick.

HLE-Lampholder
---------------------------------------------------------------------------------------------
Two terminal front mounting lamphousing. Terminals isolated from case and panel. Bright or black nickel finish. 5/16” mounting hole 9/16” centers. Panels up to 3/16” thick; 5/32” on water-tight style.

The HLE assemblies consist of three parts-a lampholder, a HL230 lens cap, and screw-on shroud lens cap that goes over the HL230. the HL230 is used to retain the lamp bulb. It may also be a color filter for bi-color effects when used with a white translucent shroud lens cap. The HLE and screw-on cap give positive conductive contact through the threads for RE shielding. The contract allows the unit to be both RFI shielded and water-tight. The HLE requires approximately 1/8 inch less space behind the panel than the HCL or HLD styles.

ORDERING INFORMATON

The HLE indicator lite consists of three parts and each must be ordered to make the complete assembly.

The text below and the two examples show how the HLE may be
Assembled as a standard or as a bi-color indicator lite depending
upon the lens color chosen.

HL-Lens Caps
---------------------------------------------------------------------------------------------
All plastic type for wide angle viewing. Shroud type for end-on viewing. Complete choice of colors and finishes. Optionally available in water tight, RFI
shielded, and bi-color versions.
