Illuminated door sills are a sweet touch but finding aftermarket ones specifically for the GV60 is difficult right now coz it's still a relatively new model. Your best bet is to check with custom automotive lighting shops or browse online retailers that specialize in universal or customizable LED lighting kits. You might need to get creative and find a universal kit that fits the GV60's sills, or even consider having them custom-made. Installation usually involves tapping into the car's interior lighting circuit, so if you're not comfortable with wiring, definitely get a professional to do it. Hit up some GV60 forums or owner groups, someone might have already tackled this and can give you specific pointers. Good luck with those doors!
