Thimson Heavy Duty Headlamp Wiring Kit. (100/90W or 130/100W)

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.

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.

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.

I decided to buy this based on Mr. Sachania's review. Package was received within couple of days of placing order. Packaging was excellent. This product seems to be sturdy and I presume it will be long lasting. It comes with ceramic holders for H4 and two 30 A fuses on each line. Relay is rated for 40 A. When connected the relay is supplied from one of the H4 OEM socket, hence protected with stock fuse. Possibility of Blown relay or burnt harness is very unlikely.Overall quality is excellent. Installed in my Aveo and it took hardly 25 minutes to do it. Checked the performance with 100/130 Philips rally and the harness is performing as expected. It is way better than the OEM harness in terms of socket quality, wire gauge and insulation. If not for upgrading the stock bulbs, this harness will help to reduce the voltage drop in OEM harness, which increases as the harness ages, and eventually reduce lamp out put progressively.Overall nice package and I would recommend the product for upgrading the Headlamps or just replacing OEM harness.

I have Maruti Suzuki S Cross. The stock headlights were very weak and my car being under warranty, I installed Philips Xtreme vision bulbs. But the bulbs made little difference. Then I planned to install higher wattage bulbs along with heavy duty wiring. Before installing bulbs, I decided to first install heavy duty wiring as DIY, so that I could check whether wiring is correctly installed and cuase no eletrical problems in my car. During testing, I found that my Xtreme vision bulbs with 60W power, were brightly lit. And this saved me the deal of purchasing 100 or 130 watts heavy duty bulbs. Wiring kit is very good, but the company provided default wiring is very weak even to support brighter bulbs with same wattage. This wiring comes with harness, that does not void car warranty. Go for it for increasing night visibility.

With in a week it fused driver side 130/100 bulb Philips Ralley which costs approx Rs 700. Replaced with Philips Xtreme Vision costs Rs1700, fused the bulb in 2 days. Total Rs 3000 wasted due to this product, don't buy.

Hello all, I had brought this few months back and installed in my wagon r old model.pros: 1. Wires are of good quality and relay seems of good quality and buildup.2. Wire length seems to be of sufficient lenfth.3. Kit was simple to install and documentation was provided on the box itself.4. Good sheathing is also provided on the wires.Cons: 1. None on product itself. But more wire tags could be provided, so that wiring kit can be fixed firmly on to the body of the vehicle.2. Screws with clamp could also be provided to fix the relay to the body.Overall, I installed the kit myself and is of good quality.Note: Do not replace your 55/60 watts to higher wattage without wiring kit upgrade.Update: Sept.2020: Main relay failed within 9 months of installation and setup. So rating stands 3. Probable root cause could be water ingress at relay connector.

I installed to my car with osram 100/90 bulbs and the light output has increased 50%. I have used the headlamp leveller(to level 2) to not blind oncoming traffic. This is a must upgrade for highway drives. The car is a stock 2006 Esteem Vxi. Check out the pictures to get reference on high beam and low beam. Thimson is not a cheap shoddy replacement for branded harnesses but very WELL MADE, QUALITY PRODUCT. We can make out the effort they put in while checking out the product. High gauge wires, quality holders used. This is made to last and available at good pricing. In summary, Money well spent.
