Instrument Cluster Blue Lenses

Hey, me again. I was just wondering...When I removed the cluster, none of the bulbs were dislodged, so could there be a problem of a bulb falling into the housing? The bulbs themselves, of course, are firmly pressed into the sockets and the sockets "lock" into the housing, so could I assume that they should be fairly secure? The only reason I ask is because I want to use the blue LED bulbs, but I want the gages to be clearly illuminated. Of course, if the bulbs I want won't emit enought light thru the lenses I'll have to use different bulbs or remove the lenses.
