PART XVI :
DO YOU NEED THOSE DRLs?
It has become mandatory in Scandinavian countries where it is persistently dark during the winter season, and their safety benefits first perceived. The safety benefit produced by DRLs in relatively dark Nordic countries is roughly triple the benefit observed in relatively bright America. [Ref: Wikipedia]
But whether they are really needed in a country like INDIA?
It will be a debate.
Now in India, many new cars come with a provision in the front bumper.
The main function of DRL is to be easily spotted by other motorists on the road. It's important that we not only be able to see others vehicles, but also be seen by others. It doesn't matter which country we are living in. we have to make sure that the DRL isn't too harsh, but just enough to be seen. DRL is mostly to make you more visible especially in the rear view mirror of other cars.
If you like,
- if you have money go for the expensive one. Philips / Osram cost you Rs. 5000 to 10000 depending upon the no. of LEDs whether 4 or 8 with complete kit.
- If you want to be cost effective go for a good Chinese make which will cost you Rs. 500 to 3000/- depends upon your need for the DRL controller.
What we have to look for:
1. Water proof DRLs
2. Standard SMD or CREE type and not the old diffused bulb type LEDs.
3. A good automobile switch
4. DRL controllers – if you want to replicate the way DRLs are supposed to work ideally.
5. Of course, aesthetics, lesser load on the battery, reduced glare etc. have to be noted.
These DRL controllers connect to the car battery and have relays which activate when the battery voltage is above 13.5-14V (when the alternator is working /engine on) and deactivate when the battery voltage is less than 12.5 volts (when engine is off). This means that no wire has to be cut.
If you don’t want the controller, you can connect through the battery directly via on/off switch in the dashboard but don’t forget to switch off, when you get down from the car. Here also you need not touch the other wiring harness of the car.
In some controllers there is an automatic switch off function when turning on the headlights, which needs a by pass connection with the original electrical circuit, which I feel should be avoided.
I personally feel that in places like Chennai where co drivers of two wheelers / four wheelers have no patience for signal lights and have a tendency to bang the back of our cars will make us to put DRLS in the back bumper, Isn’t it?
If you have your DRL story, share with us. O.K?
