Simtac 360° LED T10 / TD Pilot & Parking Bulbs (Pack of 2, Multi-Colour) – 12V Parking / Tiger Eye / Number Plate Upgrade

Stock pilot and parking bulbs on most bikes are dull, yellow and waste battery power. If you’ve upgraded to LED headlamps or fog lights but your pilot / parking bulbs still look old-school, the front end always feels incomplete.

The Simtac 360° LED T10 / TD bulbs (pack of 2) are a direct-fit upgrade for popular T10 wedge and TD pilot bulb holders, designed for use in parking lights, Royal Enfield tiger-eye / pilot lamps, number plate lights and small interior lamps. Simtac’s design uses a 360° LED layout for an even glow all around the reflector, so the lamp looks properly filled instead of throwing light in one direction.

These bulbs draw a fraction of the power of halogen – Simtac and major resellers quote up to 10× lower battery consumption compared to regular pilot bulbs – which means less load on your charging system and more headroom for accessories. T10-PRK variants are widely used on Bajaj, Royal Enfield, Hero, Honda, Yamaha and Jawa bikes wherever a T10 socket is provided, while TD-PRK bulbs are purpose-built for Royal Enfield pilot / tiger-eye housings (especially BS4 Bullet).

You also get multiple colour options (White, Warm White, Blue, Green, Red, Amber, Clear, depending on variant) so you can match your headlight or build a themed look without cheap no-name LEDs.

Buying from Under The Hood means genuine Simtac stock, fresh batches, safe packing and real biker guidance on choosing the correct socket (T10 vs TD), colour and placement – so you don’t burn money on wrong-fit bulbs.

Installation & Usage Notes

• Check socket type first. Remove your existing pilot / parking bulb and confirm whether it is a T10 wedge or TD bullet-style base, then choose the correct variant.si

• These are 12V LED bulbs meant for parking / pilot / number plate / small interior locations. They are not headlight low/high-beam replacements.

• LEDs are polarity sensitive. If a bulb doesn’t light up, flip it 180° in the holder and re-test.

• Avoid touching LED chips directly with bare fingers while installing to keep surfaces clean and cool.

• Do not force the bulb into a holder that feels too loose/tight – that’s a sign the socket type doesn’t match.

• For Royal Enfield tiger-eye / pilot fitment, ensure the wiring and holder are healthy and not heat-damaged from old halogen bulbs.

• Use colours responsibly: white / warm white for regular road use; coloured bulbs are best kept for show bikes, display or off-road applications depending on local regulations.

• If you run many auxiliary LEDs, periodically check battery health and charging voltage to avoid overloading the system.

FAQs 

Q1. How do I know whether I need the T10 or TD variant?
Remove your existing pilot / parking bulb and check the base. A T10 bulb is a flat wedge type, commonly found in parking, number plate and interior lights on many bikes and cars. A TD bulb is a small bullet-style bayonet used in Royal Enfield pilot / tiger-eye lamps. If you’re unsure, send us a clear photo on WhatsApp and we’ll guide you.

Q2. Will these fit my Royal Enfield Bullet 350?
For BS4 Bullet 350 with pilot / tiger-eye lamps, the TD-PRK variant is explicitly sold by Simtac and major resellers as a direct LED replacement, so it is a confirmed fit. For other RE models (Classic / Standard / Electra / BS6), socket design may change – please check your bulb type or contact us before ordering.

Q3. Can I use these in any bike or scooter?
As long as your vehicle runs on 12V and the position you’re upgrading uses a T10 or TD bulb, you can use these Simtac LEDs – brand listings and marketplace pages specifically call out usage on Bajaj, Royal Enfield, Hero, Honda, Yamaha, TVS and scooters like Activa i.

Q4. Are these brighter than the stock pilot / parking bulbs?
Yes. Riders typically report a much crisper, more visible glow thanks to the 360° LED layout and higher lumen output compared to tiny halogen wedges, while consuming far less power.

Q5. Will they drain my battery if I keep them on for long?
No – these are low-watt LEDs. Simtac states that their T10/TD bulbs use about one-tenth the power of halogen, so they are far easier on the battery, especially during idling and city use.

Q6. Is this pack of 2 or single-piece?
This listing on Under The Hood is clearly for a Pack of 2 bulbs (same socket type and colour), which is also how Simtac themselves package these products.
