Cyclops KTM/HUSKY BA20D LED Bulb


BA20D LED Bulb by Cyclops Adventure Sports USA.

Here is a plug and play LED bulb that fits KTM and Huskies using the BA20D bulb.

This LED bulb fits most models from 2005 to 2013 (does not fit the Husky 510, TE250 or Huskies with the bail wire that goes over the back of the stock bulb, must be the twist in style with No bail wire) (some do use H4 bulbs, SO PLEASE KNOW WHAT YOUR OWN BIKE HAS).

The stock BA20D bulb is the large round bulb that fits into a bulb holder. The bulb itself has no connector, only two solder bumps. This bulb is 3600 lumens and does have low/high capability if you have a switch, otherwise run on high beam.

– Plug and play with a KTM connector
– 20 watts on low beam
– 30 watts on high beam
– With the optional rectifier, this bulb is 2 stroke compatible. Great for your 200 or 300.

Important: Please note that all KTM and Husqvarna carbureted bikes (125 through 530) came from the factory with AC power to the headlight. Even though the bike may have a battery in stock form, the headlight is AC powered. This LED bulb will smoke itself quickly if you do not use the optional rectifier. We will not cover warranties for bulbs ran on AC power or bulbs that have suffered crash damage.


NOTE – we are an online store from our home base catering for a small select range of old school Japanese bikes as per the opening page of the website, yes we have some additional bulbs because people request them, we are not technicians or auto electricians, PLEASE YOU NEED TO KNOW WHAT BULB FITS YOUR OWN BIKE !

Hi Guys

Yes many, in fact most older carbureted enduro style or smaller bikes will take an H4 and the h4 rectifier. It is very common.

The KTM  ba20d  kit without a rectifier will only work in KTM and Husky bikes up to 2014 (ktm) 2015 (husky) that are EFI as well as the Husaburgs that where EFI

The ba20d with rec will work in all KTM EXC’s/ XCW’s from 2005 threw 2011 with the exception of 2007 that uses an H4 and the rectifier. Note that we usually ask riders what version of bulb they have, explaining the Ba20d as “looking like a small balloon”.

KTM shipped bikes with both versions in the 05 through 07 model years, but most are the ba2od other than 2007.

Not confusing at all 🙂
