“I had an issue with my car starter, and a young man named Braxton came to help. He diagnosed and fixed the problem in less than 20 seconds. He didn’t ask for anything in return. What an amazing experience! Thank you, Braxton and Car Tunes for the excellent service!”

“I had major issues with my car’s electronics following a previous installation of a car starter. The car wouldn’t even start, and it was resolved here without an issue. The owner went above and beyond to get everything fixed and working the way it should. Thank you!!!”

Common Causes of Auto Lighting Problems

Burnt-out halogen, HID, or LED bulbs reaching end of life
Corroded bulb sockets and wiring connector terminals
Oxidized and yellowed headlight lenses reducing light output by up to 80%
Failed ballasts in HID (Xenon) headlight systems
Blown fuses or faulty relays in the lighting circuit
Water intrusion into headlight and taillight housings from cracked seals

Signs Your Auto Lights Need Service

One or more headlights, taillights, or turn signals not working
Headlights appear dim or yellowish despite new bulbs
Dashboard indicator showing a burnt-out bulb
Headlights flickering intermittently while driving
Condensation or water droplets inside the headlight housing
Turn signal clicking rapidly (hyper-flash) indicating a burnt-out bulb

Auto Lights & Signals Tips

Replace headlight bulbs in pairs—if one burns out, the other is likely close behind
Polish cloudy headlight lenses annually to maintain maximum visibility
Ensure aftermarket LED or HID bulbs are road-legal and properly aimed
Check all exterior lights before long trips—a burnt-out taillight is a common reason for traffic stops
Use dielectric grease on bulb connectors to prevent moisture corrosion
If your headlights are dim, have the alternator voltage tested—low system voltage reduces bulb brightness

Frequently Asked Questions

How much does headlight restoration cost in Cornwall? +
Professional headlight restoration (sanding, polishing, and UV clear coat) costs $80-$150 for a pair. It dramatically improves visibility and is far cheaper than replacing the entire headlight assembly ($300-$800+).
Are LED headlight bulbs legal in Canada? +
LED bulbs in factory-equipped LED housings are legal. However, installing LED bulbs into reflector housings designed for halogen bulbs may not meet Transport Canada safety standards and can blind oncoming drivers.
How often should headlight bulbs be replaced? +
Standard halogen bulbs last 500 to 1,000 hours. HID bulbs last approximately 2,000 hours. LED bulbs can last 25,000+ hours. Replace them whenever you notice dimming or failure.
Why are my headlights so dim? +
The most common cause is oxidized, yellowed headlight lenses. A professional headlight restoration can restore up to 80% of the original light output without replacing the entire assembly.
