70 RR Dash bulb upgrade

Just wondering if there is an upgrade for the dash guage bulbs on a 70 Roadrunner? The stock bulbs are quite dim and yellow. Is there such thing as an LED bulb, or an Xenon bulb for this application and if so, is it just a simple plug in and go, or would you have to change wiring or relays etc...? Also wondering if you can get bulbs that are orange coloured? ( my RR is Vitamin C / Go Mango orange) and thought it might look good with orange dash lights

Here is the ones I bought they work great

for what it's worth, check your voltage on the interior illumination circuit with the headlamps on. I switched all my exterior lamps, minus headlamps, over to LED and my instrument lamps are much much brighter now. The incandescent bulbs are a very big load on the system.
