Ok, first off I know I know...it's easy to do
But heres a write up with pics for a simple DIY
1. Materials: Your clock, tape, scissors, 2 Orange transparent folder tabs from grand & toy
2. Take apart your clock like so...the buttons will fly out so dont lose them!
3. Ok the tabs are folded over. You cut one tab in half and use 1 side of it, then use both sides of the other tab...3 Layers in total! The reason for this is I notice only 1 layer makes it look yellow...3 is perfect
4. Tape the cut out tab to the clock like so.
5. Finished product (worst picture ever). This still looks yellow but as you can see on the left I have a REAL JDM VTi cluster, this clock now matches up to it almost perfectly if you were to see it in person.

PS, the dimmer has been cut (red/black wire)
LOU! even this is for EGs, but it can help you for what material you are going to use for amber clock.... and if u need help, you know where to find me
