I purchased genuine tail lights from bilal gunj for 3500Rs a pair incl wiring and bulbs, there were a few minor scratches on them which i removed with a wet sandpaper and polished the lights with a buffer and you cannot tell the difference. Honestly newer model tail lights look really bad on a old car, if your car isn't banged up then by all means go for it.
here's the number of the one and only suzuki genuine (kabli parts dealer) in bilal gunj, tell them u got the number from their old customer.
