FREQUENTLY ASKED QUESTIONS

Quick answers to common questions about fitment, installation, and product use.

Does this LED kit work with Canbus electrical systems?

Yes. The kit includes external 50W aluminum load resistors that match standard factory halogen resistance, preventing hyper-flashing (rapid blinking) and dashboard bulb-out warning errors on Canbus-equipped vehicles.

Is installation difficult, and how is the DRL wire connected?

It is 90% plug-and-play. The main bulb adapter plugs directly into your factory turn signal socket, and the flexible rubber grommet seals into the housing. The single auxiliary DRL wire (with included inline safety fuse) connects to an ignition ACC fuse in the fuse box or to your parking lights.

What is the switchback function and how does it operate?

The bulb illuminates continuously in crisp 6000K White as a Daytime Running Light (DRL). When you activate your turn signal, the white light turns off and the amber indicator flashes. Once the turn signal cancels, it automatically switches back to White DRL.

Which socket should I choose for my car?

Check your factory indicator bulb. For example, Tata, Volkswagen, Skoda, and most European/Korean cars typically use PY21W (BAU15S 150° offset pins). Honda and Japanese models generally use WY21W (T20 7440 wedge). Select the matching socket option above.

Does the kit include circuit safety protection?

Yes. The auxiliary DRL power harness comes with a built-in inline fuse holder and fuse to safeguard your vehicle's factory electrical system against voltage spikes or short circuits.

Product Details

Description

Dual-Color Switchback LED DRL & Turn Signal Bulbs (Pair)

Transform standard front halogen indicators into high-intensity Dual-Color Switchback LED Daytime Running Lights (DRL) & Turn Signals. Equipped with 42 high-output 2835 SMD LEDs (21 pure white + 21 amber), this smart upgrade illuminates in bright 6000K White while driving, and automatically switches to dynamic Amber when the turn indicator is activated.

⚡ Fitment & Socket Selection Guide

Dedicated Front Turn Signal Upgrade: Replaces factory front halogen indicator bulbs, adding crisp white DRL illumination with seamless amber switchback functionality.
Select Your Matching Socket: Available in PY21W (BAU15S 150° offset pins), WY21W (T20 7440 wedge), and PSY24W. (For example, Tata cars typically use PY21W, while Honda cars use WY21W).
Reference Guide Only: Automakers vary bulb sockets across trim levels and model years. The compatibility list below is provided for guidance and assistance only.
Verify Before Ordering: Please check your vehicle owner's manual or inspect your existing front indicator bulb base to choose the correct socket option.
Free Verification Help: Unsure? Send a photo of your current bulb or headlight indicator socket to Durvient support for quick verification.

How It Works

Normal Driving (DRL Mode): Illuminates in crisp 6000K Xenon White (6W power draw), enhancing vehicle road presence during daytime and adverse weather.
Turn Signal Engaged (Switchback Mode): The white DRL automatically switches OFF, and the bulb flashes in vibrant amber (22W power draw) with instant-on LED response.
Turn Signal Canceled: Automatically switches back to pure white DRL mode with zero delay.

Key Features

90% Plug-and-Play Installation: The main adapter plugs directly into your factory front turn signal socket. A universal flexible rubber grommet base ensures a snug, moisture-tight seal in the headlight housing.
Built-In 50W Canbus Load Resistors: Heavy-duty golden aluminum heat-sink resistors draw proper electrical load to eliminate hyperflashing and dashboard bulb-out warnings on modern BCM networks.
Inline Circuit Protection: The DRL auxiliary wire harness features an integrated inline fuse holder to protect your vehicle's factory electrical circuits.
42 High-Intensity 2835 SMD LEDs: 21 white and 21 amber diodes configured in a 360-degree cylindrical layout for full reflector coverage without dark spots.

Installation & Resistor Mounting Tip

Connect the main bulb adapter to your factory indicator socket. Connect the single auxiliary DRL power wire (with inline fuse) to an ignition-switched ACC fuse in the engine fuse box or your vehicle's parking light wire. Important: The 50W aluminum resistors naturally dissipate heat during turn signal operation and must be mounted to a metal surface in the engine bay using the included mounting hardware.

Really happy with the product, car now looks even more nice, easy to install and overall I had a good experience.

1. I have bought the DRL controller as well. The switchback from indicator to DRL feels very OEM.
2. Brightness is good.
3. Because of the DRL controller, after switching off the car, the DRL stays on for a few seconds like follow home headlights. This is a great aspect I found.

Very interesting and awesome product. LED drls and turn signal indicators built into the same bulb. Perfectly compatible for Ford Figo and Aspire. Almost plug and play installation. Except the resistor must be mounted over metal part, so that could be tricky. Used separate fuse tap cable to take power from fuse box. DRLs come on when car is in ignition and started and they really upgrade look of headlights. No hyperflashing at all of indicator (resistor prevents it well). Overall value for money. Have to see the durability. Thanks Durvient.

Great for the prize looks company fitted and easy to install . Diy installation video uploaded on my yt channel 'Shrinivas more'

Easy to install. Very good quality. Highly recommended.

Great product

Good uncommon item . Just need to check how long it's working properly.

The product is awesome looks and feels solid
installed it in my venue on my own
was an easy task with the help of durvient team they are very much active and supportive
good price and a good product

OEM products and good service

Works well.

Bought, installed and loved by several of our S-cross community members. It's an amazing addition.

The led is working properly. Good quality

Feels premium. Fit is a bit loose for VW Vento/Polo headlights but that can be easily overcome. Overall finish is premium and OEM. Suggested to buy with DRL controller so that no OE wiring will be needed to be tampered with.

Most recommended product to convert your blinkers to a DRL
It's simple to install and a DIY stuff
Prompt delivery from Durvient
Not sure abt the durability though since I installed it today and looks nice

Very good product

The switchback LED is really awesome, DRL was a missing feature on my Vento, lovely to see that I can use my existing indicators as DRLs as well.
