IMO, there are much better things to spend money on.

The electroluminescent glow produces too much glare.
And you cannot expect long term durablity from a $20 part.

If anything, I'd recommend emulating the Germans. Pick up a set of red bulbs for the factory instrument panel lamps. I think they're size # 194. The red illumination will not affect your night vision and the factory guages are more legible.
