LED Headlight Conversion Kits: V5.0, X7 and X5 Compact Explained

If your vehicle is still running halogen headlights, you've probably noticed the downsides — dull yellow light, limited range, and poor performance in bad weather. LED conversion kits fix all of that. But not all kits are equal, and choosing the wrong one can actually leave you worse off than stock. This guide covers what to look for, how our three kits compare, and how to find the right fit for your vehicle.

Why Upgrade from Halogen to LED?

  • Brighter output – A standard halogen globe produces around 1,000–1,500 lumens. Modern LED kits deliver 4,000–6,000 lumens per globe — up to 4x more usable light on the road.
  • Whiter light – Halogens sit around 3,000K (yellow). LEDs replicate daylight at 5,500–6,000K, improving contrast and reducing eye strain.
  • Better efficiency – Halogens produce 15–20 lumens per watt. LEDs deliver 80–120 lumens per watt — more light, less draw on your electrical system.
  • Longer lifespan – LEDs last up to 50,000 hours. Halogens typically last 450–1,000 hours.

What to Look for in an LED Conversion Kit

Cooling

LEDs generate heat, and without proper management they suffer from thermal throttling — as temperatures rise, light output drops and long-term reliability is compromised. Quality kits use active fans, copper heat pipes, or engineered heat sinks to keep temperatures stable and maintain consistent brightness over time.

Stable Power Output

Cheaper kits often advertise high peak power figures, but quickly reduce output as they heat up. In real-world use, you end up with a fraction of the promised light. ALTIQ™ kits are designed to hold stable wattage output, preventing flicker and delivering consistent performance on every drive.

LED Chip Placement

Headlight reflectors and projectors are engineered around the exact geometry of a halogen filament. For an LED to produce a correct beam pattern and meet ADR cut-off requirements, the chips must sit in precisely the same position as the original filament. Poor placement causes glare, distorted beams, and reduced road illumination — regardless of how bright the LED is.

Why Early LED Kits Caused Glare

First-generation LED headlights had a reputation for blinding oncoming drivers. The cause was simple: the LED chips weren't positioned to replicate the halogen filament, resulting in uncontrolled light scatter and distorted beam patterns. Modern kits — including the V5.0, X7, and X5 Compact — correct this with precision chip placement and optics-matched design, producing clean, controlled output that works correctly with your existing headlight housing.

Which Kit Should I Buy?

V5.0 – Maximum Performance
The top-tier option for drivers who want the most brightness and throw distance. Best suited to vehicles with enough clearance for a full-size kit.

X7 – The All-Rounder
Strong brightness, stable output, and broad compatibility. The right choice for most daily drivers and commuters who want a significant improvement without going to extremes.

X5 Compact – Tight Spaces
Built for vehicles with restricted headlight housings or hard dust caps. The X5 Compact matches the exact dimensions of a halogen globe, so it fits directly into H7 adapters without modification. Strong output and a clean beam pattern, in a package that fits where others won't.

Choosing the Right Socket

LED conversion kits are socket-specific. Common types include:

  • H4 – Dual beam (high and low in one globe)
  • H7 – Single beam
  • HB3 (9005) – High beam
  • HB4 (9006) – Low beam

To check your socket type:

  1. Remove the dust cover at the back of your headlight housing.
  2. Remove the existing bulb.
  3. Look for the code stamped on the metal base (e.g. H4, H7, HB3, HB4).
  4. Match that code to the correct LED kit.

If you're unsure, check your vehicle's owner's manual or contact us before purchasing.

Why the X5 Compact Exists

Some vehicles, particularly those with H7 sockets, use hard dust caps or tight housings that leave no room for an external driver. Larger kits like the V5.0 and X7 use external drivers and bigger cooling systems, which gives them higher performance but means they won't fit in restricted spaces. The X5 Compact integrates the driver into the body of the globe itself, matching halogen dimensions exactly. Same socket, same fit, no modifications required.

Why H4 Housings Can Fit Larger Kits

H4 headlights use a larger reflector bowl, which leaves more space behind the globe than most single-beam housings. This clearance allows full-size kits like the V5.0 to fit without issue, letting you take advantage of higher output and longer throw without compromising beam pattern or cut-off.

Already Running HID? There's an Upgrade for That Too

This guide focuses on halogen-to-LED conversion, but if your vehicle came factory-fitted with Xenon HID headlights, the ALTIQ™ ATOM V5.0 is the equivalent upgrade for you. It connects directly to your existing HID ballast — no rewiring — and delivers 4,300 lumens, 3.2x the peak lux output of a standard HID globe, and instant illumination with no warm-up delay. Available in D1S, D2S, and D3S socket types.

Frequently Asked Questions

Will this fit my car?
Yes, provided you select the correct socket type. Use the guide above to confirm before purchasing.

Will I get an error code?
All ALTIQ™ kits include CANBUS compatibility to prevent error codes on most vehicles. Some vehicles may still require a separate decoder — contact us if you're unsure.

Are they waterproof?
Yes. All ALTIQ™ LED kits are fully sealed and built for Australian conditions.

Do they work in projector and reflector headlights?
Yes. The LED chips are positioned to replicate the original halogen filament, ensuring correct focus and beam pattern in both housing types.

The Bottom Line

Upgrading to LED headlights is one of the most straightforward improvements you can make to your vehicle. Better visibility, lower power draw, and a lifespan that far outlasts any halogen globe. Whether you need maximum output, a reliable all-rounder, or something that fits a tight housing — the V5.0, X7, and X5 Compact cover every scenario.

Choose the right kit for your vehicle and you won't look back.
