Dialight offers many voltages, AC or DC or both, many base types, many colors.  I was buying panel and indicator lamp replacements for vintage broadcast transmitters, some of which ran their lights on AC, others on DC, at various voltages.  So I needed the variety in specifications.

In earlier projects, I was seeking replacements for the specific numbered incandescent lamps (#47, #756, etc) and I found what I needed at pinball restoration parts suppliers...

Prices were much lower than the Dialight products but they seemed fine.

In all cases, in selecting a good replacement you have to consider the use of AC or DC (since the incandescent lamps did not care) and which way the bulb is oriented relative to the target being illuminated.   Some replacement LED shoot light off the end of the bulb and others spray it around the sides of the "glass" - and some do both.
