Went in search of TVS Max 100R oil level switch. To my surprise this particular part is out of stock in most of the shops and with TVS dealer too. Finally after 2 days of hunt got what I wanted.
Parts / Tools used:
Oil Level switch from TVS Max 100R
12V bulb (small one)
Candle (to heat the tank)
Knife (to cut the tank, I don't have drilling machine)
m-seal
Cost:
80 INR
DIY
a) Fixing the switch in tank
- Drained oil from 2T tank
- Removed the tank and plugged a dummy in 2T oil hose to pump (to avoid dust entry)
- Cleaned and rinsed it with thinner
- Washed with detergent and dried
- Found a suitable area for oil level switch fitment and heated using candle
- Once when the plastic became soft, using knife cut to to few mm smaller than switch dia (instead use a perfect drill)
- Use a file to finish the hole
- Cleaned the tank again and dried
- Fitted the oil level switch and packed with m-seal
b) Fixing the indicator lamp
I don't want to spoil the stock look by adding any additional lamps. Wanted to instal additional indicator but that should not be visible outside.
- Removed the LH pilot lamp assembly
- Opened it and found lot of space inside to accommodate one more bulb
- Initially fixed a RED LED in the NEUTRAL lamp compartment
- Though the light intensity is sufficient during night time, I am not satisfied with that
- Removed LED and fitted a small 12V bulb (same as the one in pilot lamp) inside Neutral lamp compartment
- Additional bulb will share the -ve from neutral bulb
- Fitted back the assembly
c) Wiring
- Switch gets the input from Indicator flasher
- Output from the switch is connected to the additional bulb in neutral lamp compartment
Working
When the oil level is low (just touches the top of transparent window in tank) additional bulb in neutral lamp compartment starts flashing

Here are the few snaps (Sorry guys, missed out few snaps, tank with switch assembly, bulb fitment, etc)
Will upload the video of working
