Better (brighter/lower temp) dash bulb than a 57?

I've got the left side of my dash dark, and it is a PITA to get out the dash what with the pot-metal assembly/framing, so I don't want to screw around with this stuff any time soon after I fix it.

Here's the specs on the 57 bulb
# Trade No.: 57
# Design Volts: 14.0
# Amps: 0.24
# Rated Average Life Volts per Hour: 500
# Filament Type: C-2V
# Bulb Type: G-4 1/2
# Base Type: Miniature Bayonet

Anyhoo, do any of you guys know of a replacement bulb that will are a better substitute, keeping in mind that the base has to be the mini-bayonet style?

2 listings I found that are intriguing are This one at $5.99
OR this 4 LED unit at $6.49

I use the Blue LED's in my dash and Autometer gauges. Work great!! whitegauges.net

Here is my tach with only one 4 led bulb,

I'm looking for LEDs to replace the 57's in my dash lights. I'm looking here:

I'd like to find someone that has already done this and has the experience. There are lots of choices...
