So there is a picture in the how-to section, under how to change your blinker light color, of someones dash gauges. It is a picture of a car and some other designs. Is this custom made? or can i buy this. If it is custom made, how would i do it?

it is self made......but u may find some one here that would cut u the pices and send, as its best to do it urself not very hard at all....can use any color u wish and u can make it out most any thing transparent...i used a plastic candy pkg...has a red carbon fiber look....had to double it up tho a single pice of what i used was just a little to transparent...most ppl use plastic poker chips some have used milk jugs for white....the how to should explain how to pull the gauges out.....its just a few screws then ull open the casing to expose the green plastics covering the arrows then get what ever u plan to use in its place cut a replica shape install and enjoy

i think you are looking at something like what i have done on my gauges here??

its dead easy to do, get the clocks out the car and take off the front plastic, then unclip the black surround and take that out and you will find the oem green blinkers are actually small square pieces of green plastic,
take them out, trace the shape onto any colour thin plastic of you choice and cut it out, place in position of the original green plastic and put clocks back together..
