Stuck in traffic this morning, trying to get across Tamar bridge to Cornwall. I usually just drive with lights on auto but being bored decided to check out the lights on the reflection of the van in front. Went straight to main beam all good. Then i went to side lights. All good but have only just noticed all my buttons ie mfsw, electric windows etc buttons illuminated fine. However the speedo and rev counter don't light up on side lights. Is this normal ?
