Factory D-series HID on agricultural and construction equipment is available only as a premium or optional lighting package — it is never standard. Where HID is specified, it appears as D1S or D2S in a projector headlamp or roof-mounted worklight housing. All major OEMs — John Deere, Case IH, New Holland, Caterpillar, and Komatsu — now offer full LED lighting packages as the premium option on new equipment, and HID availability varies by model year, trim, and order code. Aftermarket "HID worklight kits" using H3, H7, or H11 adapters with external ballasts are not D-series applications and are outside the scope of this guide. Because no mainstream bulb reference service (Sylvania, Auxito, Super Bright LEDs) covers agricultural or construction equipment, every entry in this guide should be confirmed against the OEM parts catalogue or the bulb code stamped on your existing capsule before ordering. Call us at 647‑547‑1962 with the OEM part number from your parts catalogue and we will confirm compatibility.

Farm & Construction Equipment HID FAQs
Are my tractor work lights the same D2S as a car?
If the existing capsule has a D2S marking on its base, yes — the capsule is electrically and physically identical to the D2S used in passenger vehicles. Osram 66240 and Philips 85122 are direct replacements. Aftermarket "HID work light kits" typically use H3, H7, or H11 sockets with an external 12V ballast — these are not D-series applications and require the corresponding halogen or kit-specific bulb, not D2S.
My combine has a flickering worklight — bulb or ballast?
Start with the bulb. D2S worklights on combines and tractors are subject to heavy vibration across long operating seasons; the capsule is the most common failure point. Swap the suspect light with a known-good bulb from another position on the same machine to isolate the fault before replacing the ballast.
How do I confirm the correct bulb for my machine?
The most reliable method is to look up your machine's serial number in the OEM parts catalogue (John Deere: jdparts.deere.com; Case IH: parts.caseih.com; New Holland: nhpartsandservice.com; AGCO: agcoparts.com; Caterpillar: SIS-Online; Komatsu: parts.komatsu.com) and locate the headlamp or worklight assembly. The bulb part number will be listed as a sub-component. Alternatively, pull the existing capsule and read the code stamped on the base.
Do you ship to farms in rural Canada?
Yes — AbsoluteHID ships Canada-wide via Canada Post and Purolator from Ontario. Most rural addresses receive delivery within 3–5 business days.
Can I install D2S in a 12V tractor that originally used H4 halogen?
No — D2S requires an 85V HID ballast. A 12V halogen circuit cannot drive a D-series capsule directly. Retrofit is possible with a complete HID conversion kit (ballast, wiring harness, and compatible housing), but a projector housing is required for on-road use. For field worklights only, housing type is less critical. Call us at 647‑547‑1962 before purchasing for a retrofit application.
Not sure which bulb your equipment needs?
Pull the existing capsule and read the code on the base, or look up your machine's serial number in the OEM parts catalogue. You can also call us at 647‑547‑1962 with the OEM part number and we will confirm compatibility before you order.
