How much should it cost to get a tail light fixed?
Typically, simple tail-light issues are inexpensive to fix, while more complex problems can run into the hundreds. A basic bulb swap often falls under a few dozen dollars, whereas replacing an entire tail-light assembly or addressing electrical faults can push costs well into the hundreds, depending on the car and the part used.
Tail lights are essential for safety and legality, and prices vary with the type of fix, the vehicle, and where you’re getting service. This article provides a practical guide to what you can expect to pay in 2025, including DIY possibilities, common scenarios, and the factors that drive price differences.
What affects the price
Several factors influence tail-light repair costs: whether the issue is a simple bulb vs. a sealing or housing problem, whether the car uses traditional bulbs or sealed LED modules, the quality of parts (OEM vs aftermarket), labor rates in your region, and whether the work requires diagnosing electrical faults or replacing related components such as fuses or wiring harnesses.
Costs by fix type
Below are typical scenarios you may encounter, with approximate ranges. Prices can vary by vehicle and region, and labor rates differ across shops.
Simple bulb replacements (incandescent or non-LED bulbs)
These are your most affordable options and are often the quickest fixes. The following ranges assume you’re not replacing the entire tail-light assembly.
- One tail-light bulb replacement (incandescent): Parts $2–$15; Labor $25–$60; Total $27–$75
- Two or more bulbs replaced in the same tail-light or housing: Parts $5–$30; Labor $40–$90; Total $45–$120
For simple bulb swaps, many drivers pay under $100, and DIY replacement can bring costs down further if you have the right bulb type and access to the back of the tail-light.
Full tail-light assembly replacement (LED or halogen)
When the issue is with the entire unit—such as a failed LED module, a cracked housing, or moisture intrusion—you’ll typically replace the unit. Prices vary widely by part quality and vehicle compatibility.
- Aftermarket tail-light assembly (non-OEM): Parts $20–$200; Labor $60–$140; Total $80–$340
- OEM tail-light assembly: Parts $150–$700; Labor $70–$150; Total $220–$850
- LED module replacement within a tail-light (where available as a service): Parts $60–$300; Labor $60–$150; Total $120–$450
Expect higher costs for vehicles with scarce or premium parts, or when dealership parts are required. Labor is often the same ballpark as for a standard replacement, but parts can push the total higher, especially for luxury brands or newer models.
Electrical diagnostics and other related issues
If the problem isn’t a burnt-out bulb or a faulty unit, you may need diagnostic work to pinpoint wiring, fuses, modules, or moisture-caused damage. These can add to the bill even if the fix itself isn’t expensive.
- Diagnostic/inspection fee (to locate the problem): $50–$120
- Tail-light fuses and simple electrical checks: $5–$20 for parts; $0–$20 for labor if self-performed; or $40–$100 if done at a shop
- Wiring harness or BCM/module issues: Parts $100–$600; Labor $60–$150; Total $160–$750
- Water intrusion or housing damage requiring reseal or replacement: $60–$300 for reseal; $300–$800 for housing replacement
Electrical diagnostics and moisture-related problems can significantly raise the total cost, particularly if specialized modules or seals must be replaced or if multiple components are affected.
Where you should expect to see price differences
Prices differ based on region, shop labor rates, and whether the repair is performed at a dealership or independent shop. Cars with LED tail-light modules, integrated sensors, or premium materials typically cost more. DIY enthusiasts can save on labor but must consider safety and legality, as tail-light work is crucial for visibility and compliance with vehicle codes.
Summary
For a quick bulb swap, plan roughly $30–$75, with higher possibilities if multiple bulbs or a tight space makes labor longer. Replacing the entire tail-light assembly can range from about $200 to $850 or more, depending on OEM vs aftermarket parts and the vehicle’s specifics. If the issue involves wiring, fuses, moisture, or control modules, expect diagnostic fees and potentially substantial parts and labor costs. Always get a written estimate that itemizes parts and labor, and consider comparing quotes from a dealer, an independent shop, and a reputable aftermarket supplier to ensure you’re paying a fair price for your specific vehicle.
Bottom line: most people facing tail-light fixes will fall into one of three buckets — a cheap bulb change, a mid-range assembly replacement, or a more complex electrical diagnosis — with costs heavily influenced by part type and labor rates in your area.
