## Customer Reviews

### ⭐⭐⭐⭐⭐ Most affordable kit
*by S***. on 18 May 2021*

This is the most affordable kit that I found both online and offline. I was going to assemble a kit myself, but found this one cheap so ordered this one. The quality of materials is good and wires are thick and of a good brand, do not remember which one as its been a long time now. Used it for almost 1 1/2 years now.I had 90/100 Hella bulbs that I had used on my older Indica without the add-on harness. All cars come with an inbuilt relay wiring. With age, however, the brightness of the light reduces. After I installed the wiring kit, even the standard bulbs felt brighter. The 90/100 Hella bulbs gave good light, whiter than the 55/65 bulbs. Road was actually visible on he Mumbai-Pune Xpressway.I will be trying Philips 90/100 bulbs in a few months. I somehow feel the brightness will be more on the Philips than the current Hella bulbs.

### ⭐⭐⭐⭐⭐ This is the one
*by N***G on 7 March 2022*

Honestly more people should know about this product, I believe it's made in Hebbal, Bangalore and for an Indian made product, honestly, it's top notch.Nice quality of materials, heavy duty wiring with an additional plastic layer. The relay unit itself is robust yet sufficiently compact.Longetivity needs to be put to test but so far so good.I honestly recommend this product for anyone going for a 90/100 watt bulb upgrade. Sure Philips and Hella are great but they cost a couple thousand bucks as well.At ₹800 this is more than enough one can expect, simple, robust, effective.

### ⭐⭐⭐⭐ Strong wires but no fuse on mains wire
*by A***K on 5 August 2019*

Pros- The wires used in the cables look fat which means proper power supply to the bulbs of 130 watts. Its been 11 months and 5000 kilometres of driving with this relay and its been good till now. The brightness is same as when relay was new.Cons-No fuse in the main wire. Usually, the fuse should be next to the positive wire connector. So that there is minimum distance between the fuse and the positive battery terminal.However in this harness, there is no fuse on the positive cable and that is a fire hazard.
