How will this underglow kit change my vehicle’s look?

The Yielinth kit turns the underside of a vehicle into a controllable accent light stage. With 16 million RGB shades and 29 preset modes you can switch from subtle ambient washes to vivid, animated displays that emphasize body lines and wheel arches.

• 16M RGB colors for precise color matching and gradients
• 29 preset modes including fades, flashes and chasing scenes
• Music sync option makes lights react rhythmically
• Two-line layout with four strips covers varying vehicle lengths

What control options and features are included?

You can operate the lights either through the Bluetooth app on a smartphone or via the included 24-key RF remote. Both allow brightness, speed and mode adjustments, plus a DIY mode for custom color sequences and a timing function for scheduled use.

• 24-key RF remote for quick mode and brightness changes
• Music (SoundSync) mode via built-in microphone
• DIY mode and timing function for tailored routines

Is the kit durable and easy to install outdoors?

The strips use an IP68-rated enclosure and junction gluing to resist water and driving debris, while materials withstand -20°C to 80°C for reliable seasonal use. Adhesive backing, flexible tubing and included cable ties simplify mounting under chassis rails or along rocker panels.

• IP68 waterproof rating and sealed junctions for wet conditions
• High/low temperature tolerance (-20°C to 80°C)
• Strong self-adhesive tape and cable ties for secure mounting
• Flexible tubing and long connecting wires for varied vehicle fits

How do I power and route the strips on my vehicle?

The Yielinth kit runs on 12V DC, so it can be powered from a cigarette-lighter adapter or direct positive/negative wiring to the vehicle battery or fuse box. Long lead wires and a two-line design let you route strips to front and rear or both sides without extensive extension work.

• Works with 12V cigarette adapter or hardwired to vehicle power
• Two-line configuration: 2×35 inch and 2×47 inch strips included
• Long connecting cables accommodate most wheelbase lengths
• Soft, bendable tubing eases placement around pinch points
