On this page
These are the options you can add to a custom headlight build: angel eyes, eyebrows, demon eyes, X accent lighting, corner pieces and etched lenses. Each is explained in brief, with photos of builds we have done. For more detail on any of them, message us and we will talk it through.
Angel eyes
Shapes
Some shapes only suit certain headlights or variants.
- Full circle (flat top): full circle angel eyes with a cut section at the top, usually on the E36, E38, E39, E46, E53 and other BMWs of that era.
- Full circle: complete round angel eyes, the OEM look.

- DTM (also called flat bottom or Fxx): curved sides like the full circle, with a flattened bottom for a modern look, like newer BMWs.

- 3/4 DTM (also called 3/4 flat bottom or Gxx): the same as DTM, with the inner section nearest the kidney grilles shorter for a more aggressive look.

- Vision (also called hex): angular angel eyes like the newest BMW headlights. BavGruppe Design only.

Brand
We use two brands of angel eyes: our own KYCS range and BavGruppe Design.
- KYCS: full circle (flat top), full circle, DTM and 3/4 DTM. Cost-effective, from the same manufacturer since 2012.
- BavGruppe Design: full circle (flat top), full circle, DTM, 3/4 DTM and Vision. Brighter, with a seamless light output.
The full comparison is in KYCS vs BavGruppe Design angel eyes.
Colour
White is standard on both brands. Switchback, dual colour and colour chasing are upgrades, and each brand has its own set. See angel eye colour upgrades for what each brand offers.
Eyebrows
Carbon fibre eyebrow
BavGruppe Design eyebrows in carbon fibre only, with no lighting.

Carbon fibre eyebrow with LED strip
A BavGruppe Design carbon fibre eyebrow with a BavGruppe Design LED eyebrow strip.

LED strip within the OEM opening
A BavGruppe Design LED eyebrow strip fitted where the factory eyebrow sits. Only for headlights that have an OEM eyebrow, or the opening for one.

Carbon fibre eyebrow with optic and LED strip
A complete BavGruppe Design unit: a carbon fibre eyebrow, a custom injection-moulded optic with diffuser, and an LED eyebrow strip. Only available as a complete unit.

Colour-chasing eyebrows need BavGruppe Design angel eyes too.
Demon eyes
Demon eyes are a backlight in your projectors or dummy projectors. They work on their own, separate from every other light in the headlight, and only when the low and high beam are off. They are for show use only.
A single colour is controlled by a remote fob. Colour changing is controlled by a smartphone app.
As standard we fit one demon eye per headlight, in the low or high beam projector. For a more aggressive build we can fit a quad set, an inner and an outer demon eye in each headlight, with the hardware to support it.
Demon eyes are an add-on to a custom headlight build and are not fitted on their own.

Half X
Accent lighting from BavGruppe Design, a newer and sleeker take on demon eyes. Half X only works with BavGruppe Design DTM, 3/4 DTM and Vision angel eyes, and only in projector headlights.

Full X
Accent lighting from BavGruppe Design, the sleeker take on demon eyes for LED reflector headlights. Full X only works with BavGruppe Design angel eyes, and only in LED reflector headlights because of how it mounts. It does not suit halogen, xenon, adaptive xenon or other projector headlights.

LCI corner pieces
For the E9x M3 and the pre-LCI E92 and E93 only. They replace the OEM indicator cover and mirror the style of the E90 LCI halogen headlights.

Etched lenses
A design applied to the projector lens and lit by a demon eye. Choose from our library of designs, such as honeycomb, or ask for a custom design like a logo or initials.


Other options
- Projector upgrade: a modern projector for a sharper, brighter beam.
- Upgraded high beam: see high beam multi-LED array upgrade.
- Internal paintwork: trims in satin black.
- Sequential indicators: only as part of the advanced colour-chasing set-up with the Ghozt controller.
- New lenses and LED indicators to finish the build.
Common questions
Can I have demon eyes fitted on their own?
No. Demon eyes are an add-on to a custom headlight build and are not fitted to a headlight on their own.
Are demon eyes road legal?
No. Demon eyes are for show use only and only work when the low and high beam are off. Only white may show to the front, with amber for indicators.
Which angel eye shape is only available from BavGruppe Design?
Vision, also called hex. Full circle, flat top, DTM and 3/4 DTM are available in both KYCS and BavGruppe Design.
What is the difference between Half X and Full X?
Both are BavGruppe Design accent lighting that needs BavGruppe Design angel eyes. Half X is for projector headlights. Full X is for LED reflector headlights only.
Can I have my own design on an etched lens?
Yes. We have a library of designs, such as honeycomb, and can etch a custom design like a logo or initials on request.
