LED lights now available for all

Ask the Auto Doctor

DEAR DOCTOR: I have a 2018 Subaru Legacy with EyeSight. I dislike the look of the yellowish high / low beams against the white LED daytime running lights. I’ve been researching LED replacement bulbs and what I’m seeing mostly are conversion kits that are “plug-in play.” Should I use a conversion kit? If so, what brand would you recommend?

— Herb

DEAR HERB:: There are many companies now offering LED lights for just about any vehicle application including the interior, fog, tail and head lights. The latest LED replacement are truly plug-in play. I would not recommend purchasing any of the older version conversion light replacements. The new LED plug-in and play headlights are a bright white and use less voltage than the original.

DEAR DOCTOR: My Subaru Forester has “EyeSight” installed as original equipment. Subaru warns about adding equipment such as “self adhesive bumper guards” and other add-on items that may interfere with EyeSight features. Subaru even warns about coating the windshield, may affect EyeSight’s infrared detection, adaptive cruise control, and blind spot detection. What is your experience with EyeSight, and / or use of a product like “RainX”?

— Michael

DEAR MICHAEL:: The EyeSight system sends out a radar-like signal and bounces off an object and back to the system. To date, I have not heard of any windshield coating product, such as RainX, causing interference with the EyeSight system. But add-on parts that alter the vehicle could cause interference.

DEAR DOCTOR: Two years ago I purchased a 2000 Ram 1500 pickup with 5.2L V-8 Magnum engine with only 58,000 miles on it. The truck now has 75,000 miles on it, so I replaced the cap, rotor, PCV valve, air filter, plugs and wires. I was only able to replace four of the eight plugs. The spark plugs are sitting inside of a “heat shield” and I cannot get a socket onto them due to corrosion around the head of the plug and inside wall of the heat shield. A local shop told me I could is pry the heat shields off with vise grips, giving me better access to the plug itself. Would I be better off leaving the plugs alone? The truck is running great.

— Tom

DEAR TOM: I see these same conditions in the New England area where we have lots of snow, ice, and road salt. This is all a great combination for rust and corrosion. I recommend getting a professional to make an attempt to remove the spark plugs. Unlike the problem of Ford engine breaking spark plug problems, breaking a spark plug in a Dodge Ram truck is more unlikely.
