I replied to this a couple of days ago. Trying again:


If this link disappears, search for 5 watt push fits on amazon.

 

Thanks fir quick reply Greg, Shourd I get the T3 or T5 size, Aso, Are the speed and tach same size, Thanks

 

All the same sise. T5s for sure. The hopeless OEM ones are T3.
Note that inside the white part of the cluster, into which the bulbs poke from their holders, there is a green filter. This discolours and if it has, needs to be removed. To get at it you need to unscrew the white part of the plastic from the black part. It is a good plan to do this anyway, in my view.
There are some pics and writeup on here from me that I will try to find!

 

Cannot find my thread/posts, but here are some photos

Cluster white part off the black front part reveals the green filters

Green fiters off the cluster, these were, in fact, not darkened.

Some of the green filter locations, you can jusr see the small rivet holes that hold them on each side of the bulb hole

 

What "heat factor" are you referring to? If anything, the LEDs should be significantly cooler than the incandescent bulbs. I replaced my cluster bulbs w/ LED's probably over 2 years ago and they've been fine (just keep the alternator/battery bulb incandescent or else you can get charging system problems or the LED will just always be on w/ a slight glow)
