Review: Very good quality relay and wiring - Wiring length is sufficient for biggest of the cars. Installation is perfect, one even may not know at once that an external relay circuit has been added. It is dual relay circuit where two seperate relays control low and high beams respectively. I installed in Mahindra Thar 2022 to power 90/100 W Philips H4 blue vision halogen bulbs and the result is highly satisfactory. Can be used for 110/130 W halogens. Review: Excellent quality - Thick wires, separate fuses and relays for each bulb, easy installation. Improved brightness even with stock bulbs. Installed myself. Bought zipties to fasten the wiring from hardware shop and applied tape on the old bulb holder to prevent it from water. Feels much better while driving in the rain than before ## Features - Vehicle Compatability: Four Wheeler Lamps-H4 fitment - Made from high performance material with higher thermal resistance - Special brackets to hold relays against vibration - RTV silicon sealing from top and bottom of holder for water proofing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KNX33FS | | Best Sellers Rank | #40,540 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #53 in Turn Signal Lights | | Brand | HELLA | | Brand Name | HELLA | | Cable Type | Flat Ribbon | | Connector Type | 2-pin 10mm pitch | | Country of Origin | India | | Customer Reviews | 4.1 out of 5 stars 388 Reviews | | Included Components | 1 Pc | | Item Dimensions | 30 x 20 x 41 Millimeters | | Item Type Name | Wiring Harness Relay System | | Item Weight | 380 Grams | | Item dimensions L x W x H | 30 x 20 x 41 Millimeters | | Manufacturer | HELLA, Hella | | Manufacturer Contact Information | Hella | | Model Number | 329.317-011 | | Number of Items | 1 | | Packer Contact Information | Ws Mart | | Part Number | 329.317-011 | | Unit Count | 1 Count | | Warranty Description | 6 months manufacturer warranty from the date of sale | ## Product Details - **Brand:** Hella - **Connector Type:** 2-pin 10mm pitch - **Item Weight:** 380 Grams - **Item dimensions L x W x H:** 30 x 20 x 41 Millimeters - **Manufacturer:** HELLA, Hella ## Images ![H4 Headlamp Wiring Harness Relay System (130/100W) - Image 1](https://m.media-amazon.com/images/I/61jgBKyUHIL.jpg) ![H4 Headlamp Wiring Harness Relay System (130/100W) - Image 2](https://m.media-amazon.com/images/I/51lL5BMRpUL.jpg) ## Questions & Answers **Q: What is the difference between single and dual relay?** A: Single relay has one poweful relay for both uper and dipper And dual has separate relay for both upper and dipper **Q: Can i use it in 2016 ciaz? it comes with h7 holder.** A: It is for H4 holder **Q: Can this be used in "bajaj auto rickshaw re" to get more brightness and long throw power?** A: If your batter output is 12volts, then Yes.
