I'm about to install a rebuilt instrument cluster in my '71. I want to change the bulbs over to LED. I see that several of the vendors supply kits. I have one question. The original bulbs were all white and the factory used colored plastic (??) to provide the color for the green turn indicators and blue hi-beam indicator. Some of the kits have colored bulbs instead of all white. My question is should I get all white bulbs and use the colored plastic from the factory, or, should I get the colored bulbs and still use the colored plastic, or, should I get the colored bulbs and remove (somehow) the colored plastic? Has someone played with this who can advise me? Thanks.
