Ok I did a little test run today on how to make my gauge needles more visual/light up with my blue lights. I have orange needles and with blue light makes a purple color which = can't see.
1. So i took my gauge cluster out again today and took it apart so I could get to my needles.
2. I ended up taking off the temp needle for this test. I used a flat head screw driver and gently popped the needle off.
3. Then I took the black little cover off the needle so I could get to all of the orange on the needle.
4. Next I took my knife and carefully scrapped off the orange off the needle.
5. After that I took my white touch-up paint I had and painted the needle where the orange had been and let it dry.
6. Since the gauge still had some tention on it when i took the needle off the only way to get it set right/close enough was to plug in the cluster and start the jeep back up and let it get to normal operating temp which is around 210. So after i let it get good and warm i reinstalled the needle so it was pointing at 210.
I just had to wait until it got dark out to see if it worked and here is what i got. the needle is way brighter!!!
I know that I can do the same to the oil, battery and gas gauges. mark where the needles sit when you have power to the cluster so you can put them back to the same spot when you are done but I dont want to touch the speed or rpm until I know this answer. is the post for the needle flatened on one side like a climate control knob so you can only place it back on one way?
