What is wrong with this picture?<\/p>\n

It is a little bit blurry, but the real problem is that none of the indicator lamps on the phasor or antenna monitor are working.\u00a0 Those little incandescent 387 bulbs burn out frequently.\u00a0 It is difficult to tell, at a glance, whether the phasor is in daytime or nighttime mode.\u00a0 One also cannot tell which tower or mode is selected on the antenna monitor.<\/p>\n

It is a small job to replace them, but it does take some time.\u00a0 They currently exist in older transmitters, studio consoles, meter backlighting, and other control indicators.\u00a0 Since I began working in radio, I have replaced hundreds of these little lamps.\u00a0 I would rather spend my time on more interesting projects.<\/p>\n

The 387 bulbs cost about a dollar each and last less than a year, in most cases.\u00a0 Fortunately, there is a solution to all this.\u00a0 Enter the based LED replacement lamp.\u00a0 These little guys have the long life of an LED (100,000+ hours) in a package that is a direct replacement for the Incandescent lamp.\u00a0 They run about $5.31 each.<\/p>\n

Dialight makes a very handy cross reference:<\/p>\n

The entire cross-reference section is three pages long and is a part of their PMI catalog.\u00a0 The full cross reference .pdf can be found here<\/a>.<\/p>\n

Those Dialight LED lamps are available from Mouser, Allied, and Newark Electronics.<\/p>\n

Time is money.\u00a0 There are much better things to be doing than going around replacing incandescent indicator bulbs in various pieces of equipment.\u00a0 At the same time, it is important to know what the status of that equipment is at a glance, which is the reason for using any type of indicator in the first place.\u00a0 Using drop-in replacement LED indicating lamps with certainly save time and money in the long run.<\/p>\n\n\n
