I recently installed the Durvient RS3 3-inch Bi-LED dual laser fog projectors on my 20 Swift, and overall I am very happy with the product.
I was looking for something that would be a proper upgrade from the stock H8 halogen fog lamps, especially for driving at night during the Kerala monsoon. After checking different options, I decided to go with the RS3 mainly because of the projector setup, dual laser high beam, and the tri-colour option.
The low beam has a nice wide spread and a clear cutoff, so it lights up the road in front without just throwing light everywhere. The high beam is a completely different level, especially with the laser. The extra distance it covers is very noticeable on dark roads where there is little or no street lighting.
Another thing I liked was the support from Durvient. I had quite a few questions before and after installation, They were responsive and took the time to answer my questions rather than just giving a generic reply.
The build quality feels good and much more substantial compared to a normal replacement LED bulb. The projector feels like a proper lighting upgrade rather than simply replacing the original bulb with a brighter one.
One thing I would strongly recommend is getting the beam alignment done properly after installation. With this much light output, alignment is very important. A good cutoff and correct beam height make a big difference, not only for your own visibility but also for avoiding glare to other road users.
Overall, I am happy with the RS3 so far. The brightness, beam pattern, colour options and long-range high beam are the main reasons I would recommend it. I also appreciate the after-sales support because I had quite a few questions during the installation and they were willing to answer them.
