UNO Minda D815319 Performaxx D70/K70 Dual Horn Set for Bajaj Pulsar – 12V 70mm High + Low Tone, Pair of 2

UNO Minda D815319 Performaxx D70 / K70 Dual Horn Set – Bajaj Pulsar, 12V, Pair of 2

UNO Minda D815319 is a genuine 12V dual-tone 70 mm disc horn set supplied as a pair of 2 horns with special mounting brackets. UNO Minda's current product data identifies D815319 as the K70 horn set for Bajaj Pulsar, while the current physical retail box supplied to Under The Hood is branded PERFOMAXX D70 HORN and labelled “DISC HORN SET 12V D70 PLSR DUAL”.

That means buyers may search for the exact same product using several names: Minda D70 horn, Minda K70 horn, Pulsar dual horn, Bajaj Pulsar horn set, high-low horn pair, 12V bike horn set or simply D815319.

Exact Product Details

D70 vs K70 – Why Both Names Appear

The current physical green/blue UNO Minda box in Under The Hood stock is printed PERFOMAXX D70 HORN and the product label says D70 PLSR DUAL. UNO Minda's current online product page for the same part number D815319 uses the name K70.

For buyers, the safest identifier is therefore:

D815319

This listing deliberately includes both D70 and K70 search wording so buyers searching from either the box, an old invoice, a mechanic's description or an online listing can find the correct part.

Why Dual Tone Sounds Better Than One Single Horn

This set combines two different horn frequencies. UNO Minda currently specifies approximately 360 Hz and 440 Hz. Operating the high and low tones together creates a fuller two-note horn sound than using one identical single-tone horn.

The exact perceived loudness inside traffic depends on mounting position, battery voltage, wiring condition and whether both horns are receiving proper supply.

Confirmed / Primary Application – Bajaj Pulsar

UNO Minda's current retail page specifically markets D815319 as a horn set with special bracket for Bajaj Pulsar. Older/current UNO Minda catalogues also use the description D70 12V BJJ PLSR HRN SET.

This makes the listing particularly relevant for searches such as:

• Bajaj Pulsar horn
• Pulsar horn set
• Pulsar dual horn
• Pulsar DTSi horn
• Pulsar high low horn
• Pulsar D70 horn
• Pulsar K70 horn
• Minda Pulsar horn pair

Bajaj Pulsar has many generations and models. If your bike has modified wiring, a non-standard bracket, or a previous aftermarket horn conversion, compare the old installation before ordering.

Can It Be Used on Other Bikes?

UNO Minda's catalogue also places D815319 in the universal two-wheeler disc-horn range, and the same 12V dual-horn set is widely marketed for compatible 12V two-wheelers.

For a non-Pulsar application, check:

• 12V DC electrical system
• Enough space for two 70 mm disc horns
• Mounting/bracket compatibility
• Connector and wire arrangement
• Fuse / relay / switch circuit capacity
• Clearance from forks, mudguard, radiator, engine and steering movement

Universal does not mean plug-and-play on every motorcycle.

Do I Need a Relay?

Whether an additional relay is required depends on the motorcycle's existing horn circuit, switch, fuse and wiring. Do not automatically add a relay if the original Pulsar circuit is already designed for the correct dual-horn load, and do not bypass proper circuit protection.

For custom installations or horn upgrades on another motorcycle, have the installer check actual current load and wiring. If a relay is required, use a correctly rated automotive relay and fuse arrangement.

Want a Larger / Deeper Royal Enfield-Style Horn?

If you are shopping specifically for a Royal Enfield-style 95 mm horn rather than the compact 70 mm Pulsar set, Under The Hood also stocks separate D95 horn options.

Common Horn Problems Before Replacement

If your existing horn is weak or not working, also inspect:

• Battery voltage
• Horn fuse
• Horn relay where fitted
• Handlebar horn switch
• Loose / oxidised terminals
• Ground / earthing points
• Broken wiring
• Incorrect previous horn adjustment

Replacing the horns will not correct an underlying wiring or voltage fault.

Installation Notes

• Switch off ignition before electrical work.
• Disconnect the battery where the service procedure requires it.
• Mount both horns securely using suitable brackets.
• Keep horn openings / bodies clear of water traps and moving components.
• Confirm steering can move lock-to-lock without wire or horn interference.
• Use clean, tight electrical terminals.
• Do not exceed the motorcycle's circuit capability.
• If converting from a single horn, have the circuit load checked.
• Test both high and low tones after installation.

Buyer FAQs

What is UNO Minda D815319?
It is a genuine UNO Minda 12V 70 mm dual-tone horn set of 2, primarily marketed for Bajaj Pulsar and catalogued in UNO Minda's universal two-wheeler range.

Is D815319 D70 or K70?
The current Under The Hood retail box is labelled Performaxx D70. UNO Minda's current online product page calls the exact same D815319 set K70. Match the part number D815319 rather than relying on D70/K70 wording alone.

How many horns are included?
2 horns. The physical box confirms a set containing two units.

Is this a high + low horn pair?
Yes. It is a dual-tone set using approximately 360 / 440 Hz.

Is it 12V?
Yes, 12V DC.

What is the horn diameter?
UNO Minda specifies 70 mm.

How loud is it?
UNO Minda's current product page specifies more than 105 dB. Older Minda catalogue data for the 70 mm Pulsar horn family lists roughly 105–115 dB.

Does it fit Bajaj Pulsar?
Yes. Bajaj Pulsar is the primary named application on UNO Minda's current D815319 product page.

Does it fit Pulsar DTSi?
D815319 is widely catalogued for Pulsar / Pulsar DTSi applications. Because Pulsar wiring and brackets changed across generations, compare the existing horn arrangement if the motorcycle is modified or unusual.

Can I use it on Splendor, Apache, Royal Enfield or another 12V bike?
Potentially, because UNO Minda catalogues it in its universal two-wheeler horn range, but non-Pulsar fitment should be treated as an adaptation. Confirm mounting, wiring and circuit capacity first.

Does it include a relay?
No separate relay is claimed as included. Use a relay only if the vehicle's electrical design / installer requires one.

What MRP is on the current Under The Hood box?
The April-2026 stock photographed by Under The Hood shows ₹415 MRP for the complete two-horn set.

What warranty does UNO Minda provide?
UNO Minda's current product page states 12 months against manufacturing defects, subject to manufacturer warranty conditions.
