Let me be clear for one thing cause I own a Khyber, don't modify the meter. They are not easy to come by these days..
Lights on the other hand are easily modified at Magazine Lane.
The better thing would be buy a spare used set of the tail lights and the Instrument cluster and have it modified.
The best guy to modify or repair meter is Hafiz Jee Meter wale at magazine lane. He is very famous and does great quality work plus he can arrange another instrument cluster that can be modified. Similar is with the tail lights plalentybof tail light guys sitting around there.
Mind you the instrument cluster may cost you on the upper side of 5k modifications excluded.
And only 10% of them are doing online business. Rest is closed or Operating under closed shutters these days..
