Sounds like a Shirelles song, Baby Blue Teardrops, but these are really your standard household current night-light bulb (also seen strung on tannenbaums across the land). Ten watts with the usual E12 candelabra base, with a translucent bluish tint.

These itsy 120V neon lamps have negligible current draw and green sleeves over the lenses. Leads are 4-1/2" long with an inline limiting resistor on one. Made in the USA.

Cage the wild light bulb in order to protect it from its natural enemy, Vandalus urbanosa. Unlike the domestic indoor bulb which can be protected with a silk or paper shade, this more-endangered bulb is found outdoors or in rugged industrial habitats. Our yellow-plastic cage is available for bulbs of 100 watts or less. (Bulb should not touch plastic.) This cage is 6-1/2" long x 5" dia at its widest point. One side has a release latch for access to the bulb. It fits over a medium-base socket to protect the lamp in it. Hardware included.

And vice versa. Luckily, you’ve come to the right place, where we’re pairing clear glass 2.2V, .25A wavy, flame-shaped candelabra bulbs, 1-1/2” tall x 5/8” dia, with matching steel sockets, 11/16" long x 7/16" ID, with (2) power tabs. Sockets have a pair of clips for securing them in the light fixture. You’ll get a package of (5) bulbs and (5) sockets.

Neon indicator lamp, complete in a snap-in panel mounting. The mounting bezel is 7/8" x 1-1/2" and the lamp lens is 7/16" x 7/8". UL and CSA rated for 3/8 watts, 125 V. It has (2) spade connectors and should be great for the model railroad control panel.

These unusual, yet semi-awesome, accent light fixtures are brushed aluminum cans, 2-3/4” tall x 2-1/8” dia, and emit white light from an internal LED. Have a pair of 5/32” mounting holes on a removable back plate and (44) 5/16” dia holes spiraling around the top half. We like them wall- or ceiling-mounted for atmosphere. Rated at 85-265 VAC so they work on standard household voltage. Draw just 1W and have 2”+ leads.

If not, you need this modern accent light. In brushed aluminum, this one’s a circular light diffuser with (3) dozen 3-headed fins. Measures 3-1/2" dia x 1-5/8" below a 2-3/4” x 1-3/16” solid housing. Housing has 2” leads and a bar mount. Operates between 85-265 VAC, so standard house current works but the light needs to be hard-wired. Draws just 1W for a warm-white LED. From Lumicon.

Our uber-slick, modern wall sconce is a COB LED that draws just 1W and throws white light up and down from a 3” long x 2-3/8” square hunk of brushed aluminum that’s open on the ends. (Yes, could be mounted to light to the sides, and yes, it could be a ceiling mount.) Has a pair of 1-1/2” torsion springs to pull it tight to the wall from behind. Operates between 85-265 VAC, so standard house current works but the light needs to be hard-wired. Includes a driver circuit and leads. From Lumicon.

Fancy up your lighting with these flame-shaped LED bulbs. Base is E-14 European-Edison size, and they have a diamond-shaped faux-filiament and vertical cooling slots in copper-colored aluminum around the bottom half. You pick the warm-white 3W (40W equivalent); the cold-white 3W (40W equivalent); or the cold white 5W (60W equivalent). Also, finding E14 to E12 adapters on the web is a snap.
