So on the integra the front turn signal is made oit of two bulbs, I need the one circled in red to be white to pass inspection in my country. The problem is the bulb itself is white, but there is an orange filter inside and I cannot remove it.
My idea was to put in a bright blue bulb in there to compensate for the orange filter and make it appear white. Is that doable? Has anyone tried?
I think you should find a way to try it - even if it’s just to convince yourself it won’t work! Perhaps take the bulb out and just shine some blue light in there to see what happens.
I don’t know whether it’ll look blue or orange or greenish or muddy and dull (depends on the filter and the bulb) but it sure as fuck won’t look white :)
If the orange is only on the reflector, and the front of the bulb shines straight out through the transparent part then you might be able to block the light coming from the back of the bulb (in fact blue might work for that), but if there’s more complicated optics going on I don’t know what you can do. It’s just not very possible to get white light out if most of it goes through an orange filter or reflects off an orange surface.
