What Our Mobile Lighting Service Includes
We don't just swap the failed bulb. Every lighting service includes a check of all exterior lights — headlights (low and high beam), taillights, brake lights, turn signals, reverse lights, license plate lights, and DRLs. Catch everything in one visit.
- ◆Headlight bulb replacement — halogen, HID, or LED
- ◆Taillight, brake light, and turn signal replacement
- ◆License plate and reverse light replacement
- ◆Daytime running light (DRL) replacement
- ◆Interior dome, map, and cargo light replacement
- ◆Headlight lens restoration (polish and UV seal)
- ◆Housing seal inspection for water intrusion
- ◆Charging system check if dimming is reported
The UV Problem: Why Utah Lenses Age Fast
Every 1,000 feet of elevation gain increases UV intensity by approximately 10%. At 4,500 feet in Provo, and considerably higher in the surrounding mountain communities, vehicles are exposed to UV levels that can accelerate headlight lens degradation by 30–40% compared to sea-level counterparts. The UV-resistant topcoat on polycarbonate headlight lenses — typically 5–7 years at sea level — may oxidize and fail in 3–5 years of Utah County exposure.
A yellowed, hazy lens reduces light output by as much as 50–70% even with a perfectly functional bulb. The Texas Transportation Institute found that oxidized headlight lenses produce illumination comparable to a candle compared to a restored lens — a serious safety difference on dark mountain roads and canyon approaches.
Lens restoration removes the oxidized surface layer, restoring clarity and light output. Combined with a quality UV-protective sealant applied after polishing, a restored lens can last another 3–5 years before needing attention again. If the lens has developed physical cracks or the housing has water intrusion damage, full housing replacement may be needed — which we also handle. Restored visibility also pairs well with a battery and charging system check if overall electrical output has declined.
What to Expect From Mobile Light Replacement
Most single bulb replacements take 15–30 minutes. Vehicles where accessing the headlight requires removing a panel, airbox, or battery — which is increasingly common in modern compact engine bays — take 45–60 minutes. We come prepared with the correct bulbs and the tools for your specific vehicle.
After replacing bulbs, we test all lights with the vehicle running to confirm correct operation. For headlights, we do a basic aim check to confirm the beam pattern isn't pointing into oncoming traffic — a risk with some aftermarket LED conversions that aren't beam-pattern optimized.
Light replacement is also one of the items covered during our pre-purchase vehicle inspection — failed exterior lights are a common deferred-maintenance item on used vehicles that sellers don't advertise. Don't inherit someone else's burnt-out lights and cracked lenses.
Signs You Need Lighting Service
Beyond the obvious burnt-out bulb, watch for: headlights that seem dimmer than they used to be (lens haze, failing bulb, or charging system issue); a rapid-flash turn signal (one bulb in the circuit is failed — the circuit compensates with a faster flash rate); a taillight that only works in one of its functions (brake light on, running light off — this is usually two separate bulbs or a dual-filament bulb with one filament gone); and any warning light on the dash related to exterior lighting.
Utah Highway Patrol makes frequent vehicle inspection stops on I-15 and US-6, particularly near construction zones and high-accident corridors. A burnt-out brake light or missing license plate illumination is an easy citation that a 20-minute mobile light service would have prevented. We also check lights during our interior cleaning and detailing service — a fresh-looking vehicle with working lights makes a very different impression than one with peeling panels and dark taillights.
