How about mod the existing one?
I saw this china html about car mod. They mod to add super bright LEDs, bigger size type (can be any color u like, but the picture shows a puple one) on the cover, very neat result, just wiring work (tab to signal wire or add a switch & tab to any 12v wire) + soldering (silicone). The space required behind the mirror is very minimal only.
Result: really2 cun!!
The only thing i dont know wiring nor soldering only, else i also want to mod my wira side mirror.
Unlike what most ppl here do, just add another cover with LED (Nissan X-trail, Sentra, Kia Spectra etc) to cover existing side miror, thats really arrhhh...to me......
I wonder why so many Sifu here dont do that?? like khguan, drexchan, sky etc etc...
