Before I start this post. There’s one thing that is really confusing me? Why I’m not getting any response for these articles from you guys? Don’t you like to make your car headlights turn on automatically like the 200X cars? Isn’t that cool? Come on people, let me hear what you think good or bad 😈 .

I wrote four articles until now about how you can make your BMW lights turn on automatically at night. In the first post, I proved that this should be something easy to implement inside a BMW E36 car. In the second post, I presented a circuit diagram that will help you create the electronic circuit that is supposed to control your lights and turn them on automatically when it gets dark. In the third post, I wrote about my first attempt to implement this circuit and told you that it’s partially working but it needed some enhancements. In the fourth post, I created a video with the circuit implemented on breadboard and connected directly to my brother’s car lights. The video showed how the car lights turned on when I covered the light sensor with my hand (tricking the sensor to "think" it’s dark). So, the circuit is working correctly as intended.

In this new post, I soldered the circuit on permanent board and the end result looks like this:

I made sure that this circuit has the following:

1. Two wires for power (positive and negative).
2. Two long wires that are connected to the external light sensor. I made them long because I’m still not sure where I’m going to place that sensor. Take a look at this:

3. Three wires connected to an external variable resistor, this will allow us to adjust how sensitive the unit will be for light. Take a look at this:

4. Three wires that will deliver current from the battery directly to the headlights when it becomes dark.

With this circuit implemented, I think I’m ready to integrate this into my car. I hope in the next week, I will post a video here while I’m driving my car under a tunnel and show you how everything will work. :-). But please let me know what do you think of all this? Also, if you have any ideas about where I should put the light sensor, please let me know.

I wrote three articles until now about how you can make your BMW lights turn on automatically at night. In the first post, I proved that this should be something easy to implement inside a BMW E36 car. In the second post, I presented a circuit diagram that will help you create the electronic circuit that is supposed to control your lights and to turn them on automatically at night. In the third post, I wrote about my first attempt to implement this circuit and told you that it’s partially working but it needed some enhancements.

Today, I had the time to re-implement the circuit that I’ve been talking about and I connected it to the car. Then, I shot this video for the circuit in action. In the video, I tried to put my hands closer to the light sensor to make it "think" it’s night. Take a look at the video and let me know what you all think.

Note: this car is not mine, it’s my brother’s car and it’s dirty as usual 😆 .

I was really excited to find out that there are xenon lights that can be used to change the yellow interior lighting for your BMW E36. I’m sure that many BMW owners don’t think the yellow look that great on E36 interior especially if you have a black or other dark  interior leather.

In almost all cases white will look better for your car’s interior, but what if you could get the xenon bright white? It would look even better inside your car. take a look at the photo below:-

The Xenon Interior Lights Kit can be bought from Umnitza for a very good price $34.99 and it has 16 bulbs that can be used to replace the bulbs in:

1. Dome lights.
2. Reading Light.
3. Rear Pillars.
4. Both in License Plate.
5. The Trunk.
6. Glove Compartment.
7. Both lights that come on when the mirrors are opened.
8. Foot well if you have one.

I hope you like this kit. This is the first time I hear about it 🙂

If you’re like the rest of us, interested in enhancing your car’s performance, then I’m sure that you’ve heard of the Electric Supercharger kits. These are usually cheap and claiming that they will give you more HP (Horse Power) that can reach up to 10+hp 😆 . Well, I’ve decided to write this post to tell you all that this does NOT work. Take a look at this:

This is an example of an electric supercharger kit which claims to save your fuel, enhance your car’s power and give you a faster acceleration. Well, don’t believe everything you read. These are called "leaf blowers" 😆 because they simply can’t provide your engine with the required amount of air that a real supercharger does. The funny thing about these electric superchargers is that they normally cost less than $100. So, how the hell BMW engineers skipped adding such an important feature to their high-tech engines? I’m sure they didn’t think about this idea LOL! .

Anyway, if you want to read about real superchargers that can really push your car’s performance, then you will need to read this and this. Please pay attention to the pricing on these bad boys. They usually cost thousands of dollars and this explains why they’re not installed in all standard cars. Enjoy and sorry if I have disappointed you in finding a cheap and easy way to boost your car’s performance 😀

This is the third post in the series of how to create a control device to turn your BMW lights on automatically when it gets dark. In the first post Turning Your BMW Lights On Automatically At Night, we’ve seen how it is possible to control a light using an electronic circuit that is sensitive to light. In the second post, Turning Your BMW Lights On Automatically At Night . . . Circuit Diagram, I presented an electronic diagram that can be used as the light controller inside the car. Of course, everything I said until that post was a theory that I’m almost sure that everyone of you thought it’s impossible or at least hard to implement. At least that explains why I didn’t get any comments on that article which I’m pretty sure it’s very interesting to everyone who drives a BMW E36.

Anyway, I decided to go one step further and try to implement my theory and my electronic circuit to see if it’s going to work or not. So, I brought everything that I mentioned in the second post + breadboard to help me implement the circuit and test it to see how efficient it is going to be. After I put the electronic circuit together, I discovered that the relay is not working :p . So, I had to pull one of the car relays to use it in my test. The circuit on the breadboard looked like this (very simply):

After that, I went to the car and connected the wires to my battery and started manipulating the variable resistor until I heard the relay ticking. When I heard the tick I moved the variable resistor back a little bit until I heard the relay tick again (this time it’s disconnecting). Now everything is set up correctly. I tried to cover the CDS (Cadmium Sulfide Cell) with my hand to make it "think" it’s dark and the relay ticked. Yay! it meant that the circuit is really working and all I had to do right now is to connect the car headlights to the relay and we’re done.

The circuit that I used is this:

When I tried to connect the headlights, I left the circuit on and after I connected the headlights to the relay, I tried again and opss. It’s not working anymore. Damn it!

It turned out that my circuit which was missing the 1KΩ resistor that is connected to the transistor base is not going to make the transistor last long. This problem is happening because the transistor base is not supposed to receive high current which I gladly sent to it. To solve this problem, I introduced the resistor to protect the transistor base and replaced the old transistor with a new one. Try again … it worked for a minute and then my radio stopped working 😆

Its seems that my battery went dead because I left the lights on for some time. beginner’s mistake huh 😀

So, I removed the circuit and tried to turn my car on but it didn’t, after that I had to abort the mission and solve the car’s problem before continuing the experiment. That’s what happened last night. I hope I will be able to give you an update on this as soon as I make this circuit perfect.

What I learned until now is that this circuit is going to work on my car, but I need more time to make it work perfectly. In case you didn’t notice, I introduced a capacitor to the circuit as well which is supposed to make the headlights work for a little bit longer when the CDS is exposed to light after dark. This is supposed to avoid light flickering inside your car.

I hope you enjoyed today’s post. Until my next adventure with this project, please stay tuned to get more updates on it.
