FREQUENTLY ASKED QUESTIONS

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

How do I check if my vehicle uses PY21W (BAU15S) bulbs?
Check your turn signal housing and factory bulb. If your indicator has a clear (transparent) outer lens and the metal bulb base features two side locking pins forming an angled 150° V-shape, it uses PY21W BAU15S bulbs.
Why is it important to check my manual or existing bulb before ordering?
Vehicle manufacturers frequently alter bulb fitments across trim levels (e.g. halogen vs. LED) and facelift model years. Because the compatibility list is provided for general assistance, checking your current bulb or manual ensures you get the right socket the first time.
Will these LED indicator bulbs hyperflash or show error codes?
These bulbs feature built-in Canbus load decoders designed to prevent hyperflashing and dashboard warnings on most Indian and international vehicles. On select sensitive systems, adding an inline resistor or LED flasher relay easily solves rapid flashing.
Can I install these bulbs in my motorcycle?
Yes, provided your motorcycle operates on a 12V electrical system and has clear/transparent turn indicator pods with a 150° offset BAU15S socket.
What if I am still unsure about my vehicle's bulb socket?
Simply contact Durvient customer support with a photo of your existing bulb or light housing before ordering. Our team will verify the exact fitment for you free of charge.

Product Details

Description

PY21W BAU15S 150° Cross-Pin LED Turn Signal Bulbs (Pair)

Upgrade sluggish, dim halogen blinkers with high-intensity PY21W (BAU15S / 1156 150°) LED Turn Signal Indicator Bulbs. Powered by 44 curved 3030 SMD LED chips producing an intense 2500 Lumens of crisp amber light per pair, these bulbs provide instantaneous on/off response to give other motorists faster reaction times on highways and dense traffic.

⚡ Fitment & Socket Verification Guide
  • Clear Lens Fitment: PY21W bulbs are designed for indicators with transparent / clear outer lenses and feature 150° offset locking pins.
  • Reference Guide Only: Vehicle trims and facelift editions vary across model years. The compatibility list is provided for assistance only and does not guarantee universal fitment.
  • Verify Before Ordering: Please check your vehicle owner's manual or inspect your factory bulb base to confirm 150° offset pins.
  • Free Verification Help: Unsure? Send a quick photo of your current bulb or light housing to Durvient support before ordering—we will gladly verify it for you.

Key Features

  • Instant-On Amber Illumination: LEDs light up 0.2 seconds faster than filament bulbs, giving trailing and oncoming traffic extra distance and reaction time.
  • 44-SMD 3030 High-Intensity Chip Matrix: 360-degree spherical arrangement delivers uniform, deep-amber light fill across the reflector without dark spots.
  • Canbus Error-Free Driver: Built-in intelligent IC driver stabilizes current draw to minimize hyperflashing and dashboard warning triggers on modern vehicle networks.
  • Aviation-Grade Aluminum Body: Rapidly dissipates heat away from the LED beads to maintain luminous efficiency and extended operational life.
  • Cars & Motorcycles: Direct plug-and-play upgrade for four-wheelers and two-wheelers with 12V BAU15S sockets.

Canbus & Hyperflash Technical Note

Turn signal circuits are monitored by the vehicle's Body Control Module (BCM) or mechanical flasher relay based on electrical load. While these bulbs feature integrated Canbus load resistance that prevents hyperflashing on most Indian and international vehicles, certain sensitive systems (or vehicles where all four corners are converted to LED simultaneously) may experience fast blinking once the bulbs warm up. In such vehicle-specific instances, an external load resistor or an LED-compatible flasher relay resolves the condition completely.

Been a returning customer, As always great buying experience
Bought a pair of rear turn indicators and an LED reverse light this time. Duvient was very helpful in guiding me with the right selection. The delivery was quick and the packaging was excellent. The LEDs are well-designed, bright, and work perfectly for my needs. Highly recommended!

Excellent LED bulbs. Happy to be making this purchase. The price is justified.
At night almost all types of bulbs are visible, however, these LEDs from Durvient are great for daylight visibility.
I have attached two videos; one with normal halogen and other with the LEDs. At night the LEDs are so bright that you cannot look directly into the light source.

I feel much safer on the road now about my car's visibility to others during lane changes.

In terms of the design of the bulbs, they look really good.
