Upgraded the headlight in my RX (budget upgrade, without any electrical modifications)
HL Reflectors : DCM Toyota (Autopal make, 146mm) : 120 INR
Bulb : HS1 Osram Cool Blue MEGA 12V 35/35W: 200 INR
Connectors : H4 with custom made mating connectors for OE wiring harness : 50 INR
Labour : 0 : Complete DIY
Total cost : 370 INR
Housing the new reflector inside the OE headlamp ring is less than 10 minutes job (I have already done a similar job earlier, so little bit of experience)
Output is 200% better than the OE lamp. Low beam gives a wide & uniform spread and the high beam is more than sufficient to make the Truckies and cabbies dip their high beams.
The one on the left is Autopal reflector and the right one is OE.
Got a better lighting without spoiling the OE looks.
