There are so many threads on PakWheels about exterior and interior lights. Let's make this one stop information hub about car lights.
Kindly contribute with your knowledge and experience with different kinds of lights, bulbs etc and your recommendations for replacement of stock bulbs, lights, suggestions to improve visibility without blinding the motorists coming towards you.
Kindly mention the place of availability and estimated prices or bulbs, HIDs, Xenon etc and what do numbers like H-11, H-4, H-7 mean and what they do.
If there is any previous thread, kindly let me know, so I should delete this and follow the existing one.
