Densely placed LEDs increased Maximum Light Output for Road Visibility

[Why LEDs densely placed?]
Using IPF's own technique, the most advanced optical design provides increased maximum light output and intensity, farther reaching light beam, by shortening the physical distance between LEDs.
With efficiently designed LED placement, IPF's new LED conversion kit, the 141HLB delivers improved road visibility and safety for night-time driving.
After the model of precedent IPF's H4 LED conversion kits, this new small-sized alternative also replicates halogen filament placement for improved road visibility and performance.
Densely placed LEDs increased maximum light output and intensity for road visibility and safety which can't be fully described by lumens.

Product Dimensions & Attachment

If there is not enough space to allow full range of the LED bulb's movement, then remove your vehicle's head lights for installation.

Adopted New Post Method to take Control of Heat

• Built using Insulating Layer with Heat-Resistant Material
• Reduced the Development of Change in Appearance
• Lasts long, Minimum Appearance Change by Aging
Alike rest of IPF's H4 LED conversion kits (all-in-one drive unit), the 141HLB also places LEDs on-board using Copper Core PCB & the post method.
Designed to ensure increased light output and reliability, by taking control of LED's generating heat, and this effect is far better than conventional method.

No need to modify Deep-shaped Waterproof Rubber Cover

• Improved Bulb Fitting
• Easy Installation, Plug & Play

Newly designed 12/24V enabled Constant Current Drive Unit

141HLB Gold Flash Plating
• Using Gold Flash Plating provides Flatness than conventional Solder Leveler on Surface Finishing
• Provides broad operable Voltage Range 12/24V
• No need for Polar Check
• Polarity workable
• Easy Installation, User-friendly Design
• Suits a Variety of Vehicle Types (EV, PHEV and Autogas vehicles)
• Designed to provide Installation Ease

IPF's new design method enables electric components to be built steadily,
it ensures highly accurate detection of defects in production line which improves product reliability.

Equipped with High-Spec EMC Design & Number of Safety Systems

• Optimized Board Pattern
• Improved EMC Design to reduce Noise
• Integrated High-Performance Noise Filter
• Highest Quality Noise Reduction Performance
• Large Number of Protection Features according to OEM Standards
• Electrostatic/Pulse Protection

• Overcurrent Protection
• Built-in High Beam Indicator Lighting Circuit
Alike rest of IPF's H4 LED conversion kits, the 141HLB incorporates specially designed circuit into its all-in-one drive unit to function high beam indicator.
Replacing halogen bulb to conventional LED bulb may result in high beam indicator unlit in some types of vehicles, whereas the 141HLB offers applicability to those types of vehicles.
*Some old types of vehicles using incandescent bulbs require optional lighting circuit (P#: WA-4) to function high beam indicator on the dash.

Uncompromised Quality

• Selected highly durable Quality Parts
• Manufactured in a strict Quality Control Regime
• Meets OEM demand Standard Test
• Based on IPF's Product Performance Evaluations
• Adds muddy salted Water Test
• Conducts real Car Endurance Test
• Passed toughest Evaluation Tests
• Provides improved Durability to withstand in conceivable harsh Usage Environment
*In general usage environment, IPF's LED conversion kits deliver a sense of safety while using it for a long time as vehicle lighting is the most important security part and it offers a maintenance-free secure feeling.

///Term description///
Lumen It is the unit of the optical energy generated from an electric bulb.
When numerical value is large, the brightness of the bulb become brighter.
Candela Measure the brightest point numerically when a head lamp is equipment.
kelvin Kelvin temperature is a numerical measurement that describes the color appearance of the light produced by the lamp and the color appearance of the lamp itself,
expressed on the Kelvin (K) scale.

Light source
Halogen Halogen light bulbs are a special type of incandescent light bulb.
They are filled with halogen gas, have a tungsten filament, and are enclosed in quartz glass.
It is intend to be out of date, but still bright and gentle light in the eyes.
H.I.D High Intensity Discharge, it the new replacement technology for halogen headlights.
Brightness is the biggest advantage of an HID conversion. Not only will you be able to see farther and better at night, but other drivers will be able to see as well.
Its estimated that an HID conversion kit will increase your brightness from a halogen set up as much as 300%.
LED LED lighting is a lamp or other light that uses light-emitting diodes (LEDs) as a source of illumination.
LEDs are more expensive than traditional bulbs. They are heat sensitive, so if they are not used with a steady and consistent current, they can stop working or fade quicker.
These lights are also usually best used in directional lighting rather than room lighting, although some changes in design may improve this.
