LENSPlug-and-Play vs Cut-in Projector Lenses
Non-destructive plug-and-play lenses (H7/H4/9006) versus cut-in lenses: sizes, tools, brackets and which suits your workshop or market.
ShinVea catalog lenses come in two installation types. The choice affects the workshop time, the risk to the original headlamp and the size of the lens.
| Plug-and-play (non-destructive) | Cut-in (modification) | |
|---|---|---|
| How it fits | Mounts through the original bulb hole with an H7, H4 or 9006 interface | Installed by opening and modifying the headlamp; the lens is fixed with a bracket |
| 3.0-inch size (L × W × H) | 105 × 79 × 156 mm | 105 × 71 × 140 mm |
| Original reflector | Kept | Modified |
| Who it suits | Shops that want quick, reversible upgrades; resellers selling to end users | Experienced retrofit workshops that open headlamps |
| ShinVea examples | 3.0-inch round/square plug-and-play, ultra-short detachable, 2.5-inch | 3.0-inch round/square cut-in, ultra-short cut-in including quad direct-beam |
What a cut-in job needs
Opening a headlamp needs a headlight oven, a hot-air blower and fresh sealant to close the housing again; a front locating plate helps align the lens. ShinVea supplies these tools and sealing materials, plus shrouds, dust covers and decoders, as part of the one-stop service.
Brackets and harnesses
Vehicle-specific brackets and wiring harnesses make both types faster to install and keep the beam aligned. Many markets also want ready kits (lens + bracket + harness + sealant + instructions) for popular vehicles.
Cut-off and aiming
Whatever the type, aim the lens so the cut-off line is level and on the correct side for the traffic direction (LHD or RHD). A correct cut-off avoids glare for other drivers and helps at vehicle inspection.
FAQ
Can a plug-and-play lens be removed later?
Yes. It mounts through the original bulb hole, so the headlamp can be returned to standard.
Do you supply the tools for cut-in installation?
Yes: headlight oven, glue injector, ultrasonic cutter, hot-air blower, locating plate and sealing materials.
