By Lifestyle and Budget Insurance.com

When your car's dashboard lights start glowing, they're trying to tell you something, but many drivers aren't getting the message.

Drivers are most likely to be ignorant of what tire pressure, brake system and electrical warning lights mean, according to a new Insurance.com survey.  Almost 20 percent are unaware of what the low-fuel and temperature icons signify, results show.

Insurance.com commissioned a survey of 2,000 drivers, asking them to match the correct definition to 10 common warning light icons.

Here are the percentages of drivers who could not identify the following automobile warning lights:

  • Tire pressure warning - 49 percent
  • Brake system warning - 46 percent
  • Cruise control activated - 42 percent
  • Fog beams activated - 40 percent
  • Electrical problem warning - 24 percent
  • Low fuel warning - 17 percent
  • Engine temperature warning - 17 percent
  • Child safety lock activated - 11 percent
  • Front air bag needs service - 10 percent
  • Open door warning - 7 percent

Survey results show that, overall, drivers aren't super confident about their warning light knowledge.  Thirty-seven percent said they feel "very confident" they would know what a dashboard light means without looking it up in a car owner manual. Nearly half (49 percent) said they "might know," and 12 percent said they "probably wouldn't know."

When confidence level results are broken down by gender, men felt more confident than women:

Very confident

Men: 47 percent. Women: 28 percent.

Might know

Men: 28 percent. Women: 56 percent.

Probably wouldn't know

Men: 9 percent. Women: 15 percent.

Despite confusion over what warning lights mean, the majority of drivers surveyed seem happy with having a lot of lights. Eighty-two percent said they don't think their car has too many.

Traffic ahead

Insurance.com's survey also asked respondents about their preferences for warning lights for some theoretical situations. If  they existed, here's how many people would want the extra light:

  • Traffic congestion ahead; choose alternate route: 24 percent
  • Tire tread below 2/32 depth, legal limit for safe driving: 19 percent
  • Speed trap ahead : 15 percent
  • Mouse or foreign object in engine: 10 percent
  • Time to rest, you've been driving too many hours without a break:  8 percent
  • Heavy load -- driver and passengers exceed recommended safe car weight limit: 7 percent
  • Noise level alert -- noise level in car has exceeded safe level for driving: 6 percent
  • Blood pressure too high for relaxed driving: 5 percent
  • Safe to eat -- notifies you that road conditions are safe for eating while driving: 3 percent
  • There's a McDonald's within a half mile: 3 percent
