Each is uniquely designed according to the desired color and brightness.
Racing Gear HID bulbs are perfect for any need.

Product Features

D2S/R D4S/R
RG's genuine HID replacement bulbs use a common base (flange) for D2S/D2R (D4S/D4R). By using a removable light shield in combination, it has achieved high versatility and ideal light distribution for each.
*Spark Lumen Plus uses multi-stripes, so there is no need to remove the shade.

D1S/D3S
HID bulbs for imported cars are special HID bulbs with an integrated igniter and bulb. Compatibility with the vehicle's inverter and CPU is extremely important.
The RGHID (D1S/D3S) is an igniter of the same quality as the original equipment, so it is a perfect match for the original inverter.

When using with D2R (D4R), attach the shade, and when using with D2S (D4S), remove the shade.
*If the shade is handled incorrectly, the light distribution may be shifted or dimmed, which may result in the shade not passing vehicle inspection.

D4/D3 bulbs are mercury free

It has been specially treated to reduce heat generation and improve discharge characteristics when initially turned on.
①A vacuum is created between the inner and outer glass, and a special cooling gas is injected inside.
②A highly conductive platinum film is applied to the primary electrode, significantly increasing the initial conductivity.

Spark Lumen Plus (6000K)

RGH-RB660 (D2S/R)

RGH-RB860 (D4S/R)

Equipped with completely new "strong discharge" technology.
The only bulb that achieves a high level of balance between brightness and whiteness!

Easy installation with "multi-stripe"

The socket is the same for S/R. It can be installed as is thanks to the multi-stripes.
Optimal light distribution has been achieved for both S and R.

3000 lumens, 6000 Kelvin, improved irradiation efficiency
It boasts visibility that exceeds that of genuine bulbs.

Discharge shape

All efficiency has been improved thanks to our unique ``strong discharge'' technology, which emits light in a straight line.
Irradiation efficiency increased by 30%. Ideal discharge also increases life by 25%.
*Normal genuine bulbs discharge light in a parabolic arc between the electrodes, which increases the discharge distance and creates a thin, linear form, resulting in a significant loss in light-emitting efficiency.

Super Lumen Plus (5000K)

RGH-RB650 (D2S/R)

RGH-RB850 (D4S/R)

Much brighter than genuine HID bulbs, and extremely easy to see.
In most cases, the luminous intensity measured by a luminous intensity tester will increase after installation.
With the latest technology and a completely new concept, the discharge arc shape of the bulb light-emitting part is idealized, improving the illumination efficiency by more than 30%. This maximizes the illumination capacity of the lamp body and greatly improves forward visibility.
*This product is 5000K (white), but it is not a product that pursues color.

The luminous flux value of the bulb body has been significantly increased to 4000 lumens.
The efficiency of the discharge tube is also greatly improved, which dramatically increases the light intensity (visibility) of the illuminated area over a wide area.

Discharge shape

We have achieved "linear discharge" using our unique technology to adjust the discharge angle and reach (length) by adjusting the electrode and discharge tube shape.
*Normal genuine bulbs discharge light in a parabolic arc between the electrodes, which increases the discharge distance and creates a thin, linear form, resulting in a significant loss in light-emitting efficiency.

6300K compatible with D1S/D3S

RGH-RB63D1 (D1S)

RGH-RB63D3 (D3S)

A model exclusively for imported cars with the valve and igniter integrated!
The blue that stands out against the white gives the headlights of imported cars a cool look.
*The packaging is gradually being changed to eco cases (plain white boxes), so it may differ from the photo.

A pale white light of 6700K that is both practical and fashionable

RGH-RB867 (D4S/R)

It combines vivid blue and white.
Perfect for those looking for visibility and pale blue.
As a vehicle inspection compliant product, it has the highest color temperature in the series.

10,000K blue is perfect for those who want blue.

RGH-RB310 (D2S/R)

We have achieved a shockingly deep, ultimate blue color.
*This product does not meet the vehicle inspection standards and is therefore for competition cars only.
