DIY #1: Upgrading headlights: PS: All the DIY/Modifications done to the car are for my own convenience. None of the parts used are sponsored by any brand whatsoever, neither am I related to the seller or the company in any manner. The whole purpose of this DIY's is to help other Bhpians/guests find solutions to common problems they may face. I will not be held responsible for any warranty issues you may face after following my DIY's. I'll try my best to help and provide all the support I can. Tools required:- x2 10(mm) fixed/ring spanner.

Time taken: ~45 min.
Since our first car was also an Ertiga, we knew that the new car would also need a upgrade over the standard headlamps. Since we had tried and tested a lot of brands and different color temperature (halogens only), we exactly knew what was required. Before selling our old car I took out the headlamps from the car, but left the relay and the electrical part.
Before the new car was home, I had already purchased a new relay kit from my local accessory dealer for Rs.900. The kit is now plug and play type as opposed to the one in the previous car. The kit comes with a relay unit, two fuses (25A each, one for low and other for high beam), two ceramic holders as compared to the original plastic ones. Since the kit is already installed in the car I could only take pictures of it while it was inside the engine bay.
The original bulb: (Philips 60/55W bulb, H4 adapter type) Bulb used for upgrade: (Plasma Xenon 120/90W, H4)
We had used HELLA bulbs on the previous car, the light was bright and the throw was sufficient, but within a period of 8-9 months one of the bulb stopped working. We brought a new pair, and it worked fine for another year and a half, after that one light became a little dim and stopped working eventually. After talking to my accessory dealer, he gave me these bulbs for ~1000 bucks. The brand was Chinese, and I thought they won't last more than 6 months. But they are doing good for the past three years. (2 years on the old car one year on the new)
Install Procedure:
Since the entire wiring and connection is made on the passenger side of the engine bay, I'll be showing the install procedure of that side only.
Step 1: Open the hood:
Step 2: Disconnect -ve terminal of battery using the spanner.
Step 3: Using the long bolt, fix the relay to the engine bay as shown below. Make sure the wires are facing down as shown in the image, this is to prevent water from entering the relay. Also notice the fuse holders besides the relay.
Step 4: Route the wire for the driver side light as shown with red arrows, the small pipe is through which the wires pass. Make sure the pipe doesn't come in contact with any moving or heating parts, use zip ties if necessary.
Step 5: Behind the headlamp assembly over the relay there is a bolt that holds the front fender. Remove the bolt using the spanner. The negative wire (black color) of the ceramic holder needs to be connected to ground. The bolt after taken out may have some painted surface below it. Use some sand paper and clear the paint out so that there is proper contact with the body/ground. The same step should be repeated on the drive side as well.
Step 6: To take out the original headlamps, pull out the plastic holder gently. Once it is out, pull the rubber dust cover with one or both of it's rubber tabs.
Once the cover is out you can see the locking mechanism that holds the bulb is place. To remove the bulb you need to remove the pin, the locking mechanism is located to the left side of the bulb, there is a small metal U-shaped hook that locks the bulb is place. Press the hook and it should open. The metal part is hinged on the other end, so once the pin is out it'll move to the right side, like a door. Gently take out the bulb without touching the sides or hitting it anywhere.
Step 7: The bulb goes inside the holder in the upright position only, like I have posted the picture in the beginning. The top tab of the bulb is thicker than the other two bottom ones. Place the new bulb gently in the holder, and lock the bulb in place using the locking mechanism.
To make sure the bulb is fit in properly check from the outer side, for a hole towards the left of the bulb, you should see a small pin, that is actually the U-shaped hook. If the pin is not there, you have made a mistake and the bulb is not in proper position, remove the bulb again and proceed again.
None of the parts need huge amount of force to open or close/ lock unlock, if you need to apply force, you are doing it wrong. Check and then proceed.
The pin that can be seen from the outer side. (Marked with a red arrow).
Once you confirm the bulb is in place firmly, put the dust cap on.
Connect the ceramic holder to the bulb after fitting the dust cap.
Step 8: Connect the male pin of the relay to the female pin of the headlamp. (Original plastic holder)
The one on the left is the relay pin and on the right is the original plastic holder. This connection is important as it will control the high and low beam operations.
Step 9: After checking firmly all the connections, fittings etc. connect the main power supply (red cable) to the positive of the battery.
Step 10: Reconnect the -ve of the battery, and ensure all the connections are proper. Shut the hood. Turn on the headlamps and you should be good to go. Check for the high and low beam operations.
Output Comparison:
The light output has been tested in the car shed , as that was the only white surface available. The car was at a distance of about ~12 feet from the wall. There may not seem much difference in the confined space, but the extra wattage do add some lumens to the overall output, which can be noted during highway and city runs.
Philips bulbs on the top and Plasma Xenon to the bottom: High beam: Low beam: Some important points to remember:- This kit is entirely plug and play type, there is no need to splice any wires or do any type of T-taps.
- In case the lights do not work check for the fuse connection's first, there can be loose connections in the fuse holder. Be sure to check how firmly the fuse fit before buying the kit.
- The maximum wattage of bulbs supported on this relay is 135/100W.
- In case the bulbs stop working and you need to swap it with the original bulb, you can do so without the need to remove the entire wiring/relay unit. It supports lesser wattage bulbs as well.
