very teenage ricer mod but whatevs (not a good thing by any mean but we have all been there)
you can either change ur bulbs over to red led bulbs or run new led strips
changing bulbs is easiest and cheapest
u will need 1x 31mm festoon bulb of your choice for the roof light, pop off clear plastic replace bulb (with right polarity)
can also change boot light with a 31mm festoon
can buy them off ebay quite cheaply
for dash lights have a search on the forum as there is a whole topic on it
i suggest you dont do red as it looks tacky cheap and typical cool teenager mod
for something that will work with the car and actually practical, mebe go for some white superbright leds, more modern, still low cost, more light, no tacky coloured light
