im thinking of bringing my stock sidemarker bulbs up to the engine bay and changing the bulbs to red so when the hood is popped at shows the engine bay is illuminated red. my side markers are shaved so they just sit in my wheel wells and give this horrible little spot effect in my wheel well and under my car. looks dumb at night. so how do i change the bulb on these things. does it just twist off? any help would be great.
